I preformed the bypassing the op mod from jim p just would like to let you know that thanks to your mind and my hands I have a wonderful little amp. I upgraded the speaker with an Electro- Harmonix put there brand of tubes in I don't know if it was needed but i drilled a couple of holes in the back to help cool the insides. It was a pretty easy mod and I had no trouble doing it. I play a lot of jazz and blues so I like clean sounding amps. I own 3 amps and made my own abc block so I can turn them all on if I wish my Vox AC30 T/B was my main amp then my Hughes @ Kettner switch blade was next then the V5. I now use the V5 almost all of the time it just sounds incredible and the response from picking dynamics makes it a joy to play and it now has the power to run with the other two. The best part is if I want to play out anywhere I don't have to lug around a heavy amp just grab the V5 and my Zoom G2 and out I go. I might even try the reverb tank in the future, thanks for your time and hello to the Fretnet gang
