2001 Diaz P-XX 1x10 combo / head / pre-amp


This Amps Volume goes to there you have it.


Own a piece of history. This boutique amp was designed, built, and signed by the Amp Dr. himself, Cesar Diaz. Don't let the size fool you. The 100% hand wired Diaz P-XX is one of the most powerful, practical, efficient, and usable amps ever produced! Ahead of his time, the P-XX clearly shows the forward, creative thinking of one of the worlds greatest amp makers.



Based on their mutual quest for Holy Grail guitar tone, the previous owner had a strong relationship with Diaz. His epic collection had every classic represented and all were left with a Diaz signature or certain "thumb print" from the Amp Dr. himself.

This P-XX is one of at last ever built by Diaz and has been a jewel of the collection. Since owning the amp, I have had the pleasure of meeting the folks that were friends of both Diaz, and the amps prior owner. I will not publish the back story, but it is clear to me, that Mr. Diaz made this amp for his good friend.


What's so special about the amp?


Designed, built, and signed by Cesar Diaz - Amp Tech for Stevie Ray Vaughn, Bob Dylan, Eric Clapton, Keith Richards, Neal Young and many more.

The amp is super small and lightweight, which may lead you to believe its a practice amp. NOPE! With the first note you will be amazed, wondering how in the world this small amp fills the room. That's what everyone says that hears it. Where is all the sound coming from?

That's not it though...


The tone - It's SRV in a box, plain and simple. Plug a Strat in and you will instantly realize how much of SRV's tone actually came from the amp he was using. It's stunning. Leave the pedals at home. Glassy tone and lush reverb are the amps standard.

Plug in your humbucker set up and the amp shines in a whole new way. Clearly the P-XX was designed to cut through the mix and thrives with higher gain tones.


Versatility - This amp is a combo that coverts to a head only configuration. It also has a pre-amp 1/4" output that can directly connect to a PA via Direct Box. This amp is ready for any gig or recording setup. If you are a gigging musician, it doesn't get any easier than this. Leave the pedal board and heavy equipment home.


Quality - Fundamental to the design of a Diaz amp is the use of NOS vintage power transformers. The amp is 100% hand wired. Super solid pine cab.

    Please review the photos closely as they are a better descriptor than I.

The "iron" is all original (Power, Output, reverb driver, etc...). There is some oxidation on the faceplate screws and exposed metal hardware. The faceplate has areas that are beginning to slightly de-laminate. All wear is consistent with the amps age and use, but not abuse.  

The green tolex covering has some small nicks and chaffing, but is otherwise in great shape.  The cabinet is solid.  The hardware is all original. The speaker is original. The amp is super clean.

Original (replaced) parts ship with the amp.

Take care and Thank you very much!
