P35 “Built like the proverbial brick shithouse. There’s tone in here to conquer almost any gig”. Tom Beaujour, Guitar World Magazine.

“Without a doubt the most amazing amplifier that I’ve ever had the pleasure to record or play, and I’ve heard them all! Penn amplifiers are so tight and defined that he actually makes my job easy. Any guitarist who is even remotely serious about having the ultimate tone live or in the studio owes it to themselves to check out a Pennalizer.” Joseph DeMaio-  Owner, Engineer Shorefire Recording Studios. Long Branch, NJ

“Who says they don’t make amps like they used to? In the studio the Pennalizer 1×12 opened up gave me the punchiest OD I’ve gotten in years and then the 4×10 gave me that classic type tone without any harshness. Thanks Billy”!! Marc Swersky Independent producer/writer. “The Bodyguard” soundtrack, Hilary Duff.

“The clarity and articulation of this amp is something to be experienced, boy does this thing have TONE! I can not overstate how much Billy & Penn Inst Co deserve a “10” for their/his wonderful Customer Support. I can’t imagine ever owning another amp that sounds THIS good – this is the sound I’ve been striving to obtain”. Brian Ward.

“I’ve been playing a Pennalizer 50 since 1997. This is the perfect amp, the kind you thought was only made in the 50’s and 60’s, but without the noise! All tube, all hand-wired, and totally amazing. The tone is something you will not believe until you hear it; there’s no reason to buy an old beat-up amp to get that “personality” you’ve been looking for in your sound. In fact, there’s not really a reason to buy any other amp. They will build you an amp just the way you like it, they stand behind their product and your guitar will sing like you’ve always wanted it to. This is, quite simply, the best amp there is for people who are in pursuit of the perfect tone.” John Lehman, Memphis TN

“Best Amp I’ve heard to date”! Tom Masco

“Compared to anything on the market, nothing will beat the quality and warranty on these amplifiers”. Matt Whatley, Klipsch Audio

“Chords and solos sound thick, meaty and focused, and the reverb does a good job of adding tonal air”.Guitar Player Magazine.

“This is the last amp I’ll ever need. I’ve been through many pieces of equipment, including my last amp, Rivera KHR 100, but nothing has compared to the features, quality, and tone of this amp. If it was stolen, I would not think of replacing it with anything that wasn’t built by Bill Penn.” Scott Pilla.

“The amp really kicks butt. It is smooth and sweet at low volumes, and a monster while cranked up. It breaks up early enough to get great barking EL84 crunch at reasonable volumes. The amp seems like it was made for Scott’s guitars. The Tele’s sound particularly great.  I understand he wanted an amp with EL84s which are his favorite tube, and you delivered it”. Ian Anderson,  Lentz Guitars

The build quality on the Pennalizer is really top notch. The amp really sounds great. I really dig this amp!! – Erik Johnson

“This amp sounds great with single coils or with humbuckers. It can sound sweet and clear; it can sound gritty & biting with a few adjustments. Rhythm sounds are smooth and clear, balanced. Lead sounds are distinct, and all sounds are harmonically rich and pleasing. This amplifier could be used effectively in almost any style. It’s simply a great-sounding amplifier and one of the finest I’ve had the pleasure of using”!  Mark Williams

“I’VE TRIED EVERYBODY’S AMPS AND PENN AMPS GET THE BEST SOUND SONICALLY POSSIBLE, I DON’T KNOW HOW BILLY DOES IT BUT THE PROOF IS IN HIS QUALITY PRODUCTS”!!!!!!!!! “ONE LISTEN AND YOU’LL BE A BUYER FOR LIFE” – STEPHEN MARK PASCH -WORLDWIDE WORSHIP LEADER

“All I can say is wow! This is the one I’ve been searching for quite some time. I didn’t know amps could sound this good until now. The Pennalizer is a tone machine and is superbly crafted to last a lifetime”. Jonathan Dyer

“I love the reliability and tone of all my Pennalizer’s. They endure a lot of hard use in the studio and on the road. I highly recommend any Penn amp to any one who is looking for a high quality product”. -Ed Sullivan –Big Ed and the Sidepockets

“My Pennalizer  is all I need to cut large or small venues. It works well in the studio too because it sounds great and is remarkably quiet. It even stands up to all the gigs and sessions without fail, every time. I count on my “Pennalizer”.  Steve Johnson
