I did the same as you Parker. I blame Scotch and Ken for my buying this amp. They just made it sound so dang tempting.
Now that I've received it, i get exactly what they were trying to describe. Big ,fat, luscious bass. Perfect bass in my book.
Haven't had time to play much but 12 o'clock on the dials does sound about right. Have to tone down the bass in my house or it shakes like crazy.
Also, this amp has tons of power. I've had a GB 600, EA Amp i800, Little Mark III, TC RH450 and this is at least as ballsy as any of them. And like the Little Mark, it's kinda a set it and forget it amp. Simple, clean.
I would love to have someone explain more about how, what the "drive" really does. And also how the "gain" knob differs from other amps. Ken, any thoughts?
Loving it so far (2 days!).
Hello! First, TBer Eublet did a lot of work doing plots of the drive control that helped me understand and describe what I'm hearing. With the drive 'off' (full counterclockwise), it does nothing (duh, but just so that is clear

). As you turn it up through about noon or 1 o'clock, it gradually eliminates deep bass and treble. So, it is what I call an 'old school' knob within that range. It kind of turns a modern, two way ported cab (deep bass, full extension into the mid to upper treble) into a cab that sounds like a one way sealed cab (tighter, punchier bass, and a top end that stops at the upper midrange).
Cool so far. Then as you turn the drive up past aroiund 1 o'clock (although it varies with gain), it seems to actually add midrange and gain, which results in snarl and outright grind eventually... now kind of emulating a one way sealed cab with a tube amp pushed hard.
The magic comes with the gain control used in combination with it. The gain is unusual (IMO) for an all solid state amp, since similar to a real tube pre, it will add harmonic complexity as you turn it up, from a nice bit of 'hair' to the note, to a nice 'give and warmth' feeling, all the way through screaming snarl.
When you use the two together, there are a LOT of 'tubey' things that you can get from the amp. I'm not a 'distortion guy', but I do like to push the gain a bit with my P, and then dial in a bit of drive to 'warm and tighten' and 'old school up' the tone. When I'm playing my 70's style J, I leave the drive off and lower the gain a bit to keep it more 'open, quick, and relatively clean'.
Wonderfully creative front end to this amp (and the TH500, which behaves identically to the 350).
