Re: [Harp-L] Fender Blues Junior - Tube Substitutions For Harp

[John Kerkhoven <solo_danswer@xxxxxxxxxxxx>]

A few years ago, following advice on this list, I swapped a 12AX7 for a 12AU7 to help control feedback on a Seymour-Duncan 84-40. There was a drop in volume, but the feedback was now under control. No troubles since.

This amp comes with 3 12AX7s. I swapped just the first.

Don't know how this transfers to a Blues Jr. YMMV

All the best,

John

I'm helping a friend who has just purchased a used blues jr. and I am sure you could save us some valuable time and money so we can just purchase  AT's AY's or AU's...
