Isn’t V3 the second tube from the right viewed front of amp ?? ( circuit board shows V3 )

Yes you’re correct my mistake, still the drop to the 12AY7 gain 40 made the better improvent to me using a guitar with HB I think the 5751 or 12AT7 do not drop enough to hear any real improvement but the 12AY7 warmed the sound and dropped the gain. Worked for me

The 12AT7 would be too low a gain drop. The V1 position works well with the 12AY7 or 5751 .. even the guys at PRS suggest it

Ok I’ve now tried a JJ AY7 in position V1 and this makes the amp far more usable for other genres .. clean channel is less boomy with HB pickups and sounds good, lead channel with gain on 10 o clock sounds like classic rock and I can now add a tubescreamer to give it a boost into heavy rock /...

Also why is it best swopping V3 and V1 ?? Interested to know why this is

i tried a 5751 in V3 and it’s more to my liking and cleans up with the guitar volume nicely I’m running it now with gain on 8 o clock approx Any reason why I couldn’t try a lower output pre amp tube such as 12ay7 or 12at7 in V3 to really drop the gain levels or could this have a negative...

I’m looking at trying different pre amp tubes such as 5751 and 12AY7 in my MT15 Looking at the front right to left can someone suggest if V1 is the best one to swop or V2 or even V3 ? I’m looking at reducing the gain on the lead channel only Thanks
