    JTM 45's are beautiful as they are - saying that the Rockytops I've heard have more gain than the originals. Originals put out about 33 - 35 watts, they are a comfortable volume. Stick it thru 2 Greenbacks.

    Best, Pete.

    Mine sounds really really good the way it came. I like EL34s better than KT66 but just bias and go for that. Mine is a very useable volume level as is, and the cleans are beeeyootiful. Mine's in a 1x12 combo box with Cannabis Rex speaker, what a match. YMMV but I'd just enjoy it for awhile before messing with it :p

    yikes!
    i just finished playing it on my lunch hour.....and as they say..that was about the most fun ive ever had with my pants on.
    it does have a tad more gain than the old ones as i remember. i cant see why you would want to mod yours. jesse is great at building these. this amp has to be one of the quietest and harmonicly full amps i have ever played. purple on my purple/salt/pepper 4x10 looks killer too. i cant wait to get off work and go play some more!

    Do you like the 10,s better than the alnico 12,s? I was thinking of getting a 410 to match this head.

    well i havnt tried it with 12's yet,..... im using a 4x10 cab i had made with eminence legend alnico's(blue 20 watt). i have been using super reverbs mostly the last ten years so it seemed like a good idea with the added benefit of being more portable. but...just in case.... i ordered a purple mojo 4x12 last week....hehe....
