This amp has been my right arm for many years. It is damn heavy, but I call it 80lbs of tone. I don’t take it on the road much as I do a lot of fly dates but play a lot with it locally and regionally. I have used everything under the sun for backline, but every time I get home and plug this thing in it feels like home. Lots of power and I love that I can plug any guitar into it and I feel like the character of the guitar is the feature. I run a pretty neutral sound and I use stomps for dirt for the most part. I pulled both the center tubes out and leave it at the 100W setting. To my ears the lower power settings don’t make it less loud (It is loud af) it just seems to saturate earlier. The trick for me was to use both channels at the same time. There is an input that blends both channels which works great for me. I run the dirtier channel just before breakup and if I need it a bit cleaner, I just dial out Ch 2 or turn up ch 1. Highly recommend.

Roland Beaulieu,

I’ve had my “The Twin” for many years but as it is mainly a bedroom amp at the moment I thought I’d try (as the manual says) taking out the middle two power tubes. Yes, it still works and yes it is now a bit easier to find a comfortable volume level. This amp is still an amazing piece of kit but now doesn’t scare off the cat so easily.

GordRD,

Just got mine back from a tune up. Caps replaced, all NOS tubes – its like a new amp. Sustain and saturation at low volumes are now possible on the lead channel. And the clean channel sparkles.

Jim H,
