Hey David, SC is correct, it will just sound like me cranking the gain way up. Also I have Ultrasonic PUs in my Anderson (it was one of the first built and first one in Australia back when they used Ultrasonics). The Ultrasonics are quite flat (reference series, very even bass, mid, treb) compared to other PUs so my eq settings reflect that. My old rhythm patch (see MP2 patches) is the highest gain I use these days (and needs the gate). I now use the new(ish) rhythm patch for both rhythm and lead and use the volume pedal (CC master vol) for lead volume boost. It's a 5 warm vintage voice and has heaps of gain, great for rock. My old rhythm patch was good for 80s/90s covers, Billy Idol, Poison, Mr Big, Skid row etc but generally way to much gain for how I play now.
Maybe it's better to compare the 3 different tubes I've had in the MP2. Also I went from MP1 to MP2, the MP2 has lots more gain than MP1 (not that I needed more).
Original Chinese bottles, nice tubes great sound heaps of gain
Tried Boogie STRs (JJs most likely), nice tube plenty of gain, tight, greatttt feedback (just sings) but I found break up a bit on bottom E and not 3D at all.
Mullards, heaven on a stick (to my ears), again plenty of gain but sooo responsive to how I play.
When I get a chance I'll record some sound bights and post them and maybe try a super high gain for you to hear.
Seems the long plates are out of stock at the moment but the short plates are available. If you can afford $50, try a pair, I promise you won't dislike them, are they the tube for you ? that's up to your ears but IMHO they are better than both the original tubes and JJs in MP2. Oh and my 2nd MP2 came with a pair of EH 12AX7s, best thing I ever did was replace them with the Mullards, they don't sound good in MP2 (again IMHO).
