Amp FAQ
-
What amps do you use?
I use a Fender Blues Deluxe Tweed NOS edition for most shows, and a Fender Hot Rod Deluxe for larger gigs.
-
Is the Fender Blues Deluxe loud enough to play at a gig?
Yes. This amp is capable of volume levels loud enough for most small gigs. The only question is how much clean volume you can get. Because it’s only 15 watts, when you start to crank it up, the power tubes get driven pretty hard, generating a nice overdriven tone. However some people want super clean tone at loud volumes, and this amp will not deliver that. It’s tone at loud volumes will have some tube distortion. I suggest trying it at a store where they’ll let you crank it up for a minute to test.

What’s the difference between the Fender Blues Deluxe Tweed NOS, and the standard tolex version?
The Tweed NOS Blues Deluxe that I bought had better tubes ( Groove Tubes ) and a better speaker ( Fender Special Design ). I compared it to a regular tolex version. The tone on the tweed edition was brighter, had more musical sounding distortion, and felt more “alive”. I calculated that if I bought the standard tolex edition, and then bought a new set of power tubes and a new speaker, I’d probably spend the same amount of money as if I had bought the Tweed version, but still have the tolex cover instead of the Tweed. Since I liked the Tweed look better, I bought it instead of dealing with replacing tubes and speakers.
-
What’s the difference between pre-amp tubes and power tubes?
Standard guitar tube amplifiers have 2 basic types of tubes. Small tubes, and big tubes. The small tubes are called pre-amp tubes. This is short for Pre-Amplifier. It means that they handle the sound before it’s amplified very much. These are the first tubes that the sound passes through when it enters the amp from your guitar.
The big tubes are called power tubes. They take the relatively small level of sound from the preamp tubes and amplify it. They then pass the sound into an output transformer, which amplifies it even further. Finally the sound ends up at your speaker.
-
What is preamp tube distortion and power tube distortion?
Preamp tube distortion is when your amp is receiving a larger signal from your guitar than the preamp tubes can amplify. If a preamp tube can multiply the sound by a factor of 5, but it’s upper limit is 25 millivolts (not real specs), than the highest input you can give it without it distorting is 5 millivolts. If you put in sound at a level of 10 millivolts, the tube cannot amplify it cleanly. It causes the tube to cut off the highest peaks of the sound wave, which we call distortion.
The same is true of the power tubes. If the preamp tubes are sending more voltage to them than they can amplify cleanly, then they too distort. However, they sound distinctly different than preamp tubes when they do this.
Preamp tubes tend to sound small, and fuzzy when overdriven. You can hear this in most amps that have a “distortion” channel. By turning the gain all the way up, and the master volume all the way down, you are effectively pushing a lot of voltage through the preamp tubes, but cutting it to a reasonable level before sending it to the power tubes. Thus, the preamp tubes will distort a lot, but the power tubes will not. The resulting sound is heavily distorted, but like I said, will tend to sound fuzzy.
Power tube distortion is quite different. If the preamp tubes are operating cleanly, and creating a large enough signal to push the power tubes into distortion, the resulting tone is smoother, sounds more muscular, and is much “brighter” than when the preamp tubes are distorting.
In reality, good tone is usually a combination of both. Stevie ran his amps pretty much on 10. At these settings, the preamp tubes are distorting some, and the power tubes are distorting a lot. This created a rich, thick, muscular tone that so many people have tried to copy since.
-
You have a Blues Jr right? not a Blues Deluxe?
That is correct. My main amp is a Blues Junior. My other amp is a Hot Rod Deluxe which I only use for larger gigs. The first couple lessons feature the deluxe, the rest are the blues junior.

I’m looking to get a Blues Junior Tweed, but I’m a bit worried about getting a clean tone at a higher volume. I know you use several EQ pedals for a nice clean boost - what do you think about compressor pedals? I’ve used them before, but never with a lower wattage amp like the Blues Junior. Opinions? Great site by the way - excellent playing too.
A compressor will not add any clean headroom to a small amp, it might actually take it away! Here’s why: Once you get the amp cranked, when you strike a really strong chord, you send a lot of signal to the amp, and cause it to distort. If you pick lightly, it cleans up really nice. The reason is because when you pick lightly you’re not sending much signal to the amp, so even though it’s cranked, it’s able to amplify the small signal without distorting.
A compressor pedal evens out the signal level between your hardest picked notes and your softest picked notes. On an amp that’s not cranked, this can ensure that you’re getting the most volume out of every note regardless of how hard you pick it. However, for an amp that’s already cranked, what you’re essentially doing is taking away your option to pick lighter and clean up the distortion for some notes because every note is close to the same volume.
-
Could the Blues Junior be too loud for home/learning/non-gig use where you still want to overdrive the tubes some?
The Blues Junior has both preamp and master volume, so you can get decent tone at very low volumes. Always sounds better when cranked, but low volume practicing is possible.

Anthony,
I don’t know if my last question went through, so I will ask again. I have a Marshall MG250D FX stereo combo amp. I love the SRV sound. I play a Fender Mexican Strat with Fender Bullet ten gauge strings. I am trying to get as close to the SRV sound as possible. I am close but still not there. You seem to have the right sound and I was wondering if you had some ideas on how I could get that sound. Maybe a pedal would help and/or some Fender Texas special pickups. Keep up the great work, I have learned a lot and I look forward to hearing back from you. BillyI hate to say it Billy, but a Marshall amp is always going to limit your ability to get the tone you want. The Marshall amps are wired differently in the tone section and they’ll never sound like a Fender. I used to own a THD Univalve amp which was very nice, but sounded very much like a Marshall. I eventually had to sell it because the high end was too brittle, and I couldn’t get a Fender-like tone out of it.
-
Will the Fender Texas special pickups help get me the sound? What pedal would you reccommend for a very bright and clean sound? Billy
I’m not a huge fane of the Texas Specials (even though I own a pair). The reason is because they’re kind of a “dark” pickup. I much prefer a higher end pickup like Lindy Fralin Blues Specials or even Vintage Hots. However, the Texas Specials will sound better than most stock Fender pickups.
As for a general bright clean sound, a Tubescreamer set on high, without much gain, and the Tone maxed out will give you a bright tone without much distortion. Unfortunately you lose a little low end in the process.

Anthony,
You have shared the settings you use on the Blues Junior. Since I only have the Fender Hot Rod Deluxe can you share your recommended settings for that amp. Would the pedal settings be the same as when using the Blues Junior? Have you ever tried a tube screamer? What did you think? You can respond to my email if it is easier or if you don’t think these questions have general relevance. Thanks.

If I were playing through the Deluxe, my approach would be similar with one big exception. I could not use my boost pedals with the clean channel of the deluxe because the amp is not being overdriven very much there so the volume would get much louder. I’d have to switch to the overdrive channel, which I would have set for a mild amount of distortion, the use the pedals as I do with the Blues Junior.
-
I am wondering if you can list your settings for your Fender Hot Rod Deluxe? I have spent hours upon hours trying to dial in “that sound” on it, and am getting nowhere! I Greatly appreciate any help, and, your site here is AMAZING. Keep up the GREAT lessons!
I’ll have to do a demo video of that amp, can’t name my settings off the top of my head, but I’ll try to remember to work it into the lessons.
-
I love the SRV Sound, I like your sound too and I definitly want to get as close as possible to that -
at home! But there is no way to play a tube amp at a students apartment, although with an amp which has a master volume… So, did you have any experience with any kind of moddelingpreamps or other little practice amps to get near to that beautifull sound?A Blues Junior with the Gain knob almost all the way up, and the Master volume way down gives some beautiful tone at low volumes. Also, the Nobels ODR-S with the distortion pretty much maxed out will give you decent tone at low volumes too. The part you’re eliminating is Power Tube distortion, and the effects of the speaker being pushed hard, so it won’t be the same, but it beats getting evicted
-
I own a fender hot rod deville and was wondering if you have played this amp and if so what you think of it . thanks
I have played through one and it’s way too powerful for anything I need. A ton of clean headroom, but your ears will bleed before you get any power tube distortion out of that amp.

can i hook up a blues jr to an extension cab and how?
The speaker jacks are a little hard to get to, but if you look under the back panel of the amp, you can see where the cord connecting the internal speaker plugs into the amplifier chassis. There might be an extension jack there, but if not, you could disconnect the internal speaker, and connect an external cabinet, make sure it’s 8 ohms though to be safe. Should probably ask someone at your local store to check it out first and make sure it will work.

Hi, a question from France… (excuse my bad English)
I love SRV and I want to know if a Stratocaster with texas specials + amp Fender 65′ (reissue, 22 watts) and Jacques pedal (overtube) are ok for the SRV sound ?
I’ve hotrod amp, but to loud for me…
Thank’s for your good job
I’m not familiar with the Jacques pedal, but the guitar and the amp sound like they might do the job. 22 watts will still be pretty loud but it might do the trick.
-
hi guys!
i m french so sorry for the words that i’ll use!
i own a fender blues jr !and i like your sound on the videos!
could you give me all the pedals name and other that you use with this amp to get this amazing sound
thanks so much for your help and website
take care
nikko.south of france.montpellierNi Nicolas,
Check out the gear demos videos to see the pedals I use.

i have a fender twin reverb, do you think it is possible to get that srv tone from a twin?
It might be kind of tough to get that tone from a Twin because it’s so powerful. I used to own one of those beasts and they are loud!

I have most of the gear you use already and I have learned that most tone comes from the player, not mainly from the gear. I also have tried out many different set ups and it is hard to say that if you have a strat, blues jr, nobels, etc.. and set them to your settings, that it will sound the same as yours. Because in most cases it just won’t happen. I’ve found that every strat / amp ect.. has it’s own unique sound. That being said, I am ordering a Grosh but -it will not be ready for 4 months. In the mean time I’d like to pick up a Mexican strat and if you don’t mind “copy cat” yours. I don’t know were to begin, what year range should I be looking for? Is it alder or ash body? Is it a Brazlian Rosewood neck? Pick ups, Rocketfire Total 60’s HW Vintage Strat, will they come stock or have you done any mods to them? The wiring - have you changed anything or added the blend control like the Grosh has to it? Thanks and sorry for all the ??? Mike Boston MA
My mexican strat is from approximately 1996 and originally came with a humbucker. I have no idea what kind of wood it is, but I do know that it’s fairly heavy. I didn’t buy it on sound because at the time I was a college student, I bought it on price, sub $600. It actually sounded quite bad with the stock pickups. The Texas Specials were an improvement, but the Rocketfire pickups have made it a great sounding guitar.
