Power Amp Power Amp Power Amp!

A bit of history with this style.

We made an original Beetlejuice PA50 with similar pin stripes for Halloween this year. It took forever. Figuring out how to tape it off correctly, not getting the colors to bleed together, working with glow paint, etc… real nightmare. We had thicker stripes on the original, and this set that had thinner stripes that we never finished. We figured out how to finish off this second set with the thinner stripes finally and it looks awesome (not to mention the purple LED glow inside). This second one makes it one of two in existence, and I doubt if we will ever subject ourselves to doing a third! Please no Kyle!

Ok, back to the normal stuff…

Finally, the perfect power amp to compliment your Ceres, Vesta, modeler, or any other preamp! Our goal for this product was to put the excellent power section found in our amp heads into the smallest package possible. Weighing in at only 12.8 lbs (5.8 KG), it packs a huge punch in a compact, portable unit. The PA50 is probably the most compact 50 watt all tube guitar power amps on the market.

With the myriad of tone shaping controls the PA50 will be right at home with any preamp, distortion pedal, or modeling unit. The HiFi / Guitar switch is the secret weapon for running your modeler, or if your preamp is particularly dark. The extensive set of NFB (negative feedback) controls allow for near limitless tone sculpting options, garnering both the best modern and vintage tones.

The PA50 includes our first-ever built-in bias monitoring circuit, as well as individual adjustments for each power tube. This allows for the use of slightly mis-matched tubes, as well as purposeful mis-matching to generate different harmonic content.
