i.e. without a TS out front. I know some amps like Rectifiers and original 5150/6505's just can't really cut it without a boost, but the II/+ series amps feel just about compressed enough to get away with it, given the right settings. I'll put some clips up tomorrow of boosted vs unboosted, but after playing around I've come to realise there's a certain grittiness and palpability to be had from an unboosted amp of that ilk. I've currently got a 6534+, and a Marshall JVM410h, and both sound gloriously aggressive without the Maxon in front. I find the boost adds a smooth gloss over the tone that takes out some often-needed ugliness. If everything you're working with is coming straight from the head then it tends to be a little gnarlier and adds a touch more definition (or, rather, doesn't take any away). Since a TS cuts more, I find when taking a boost off you have to compensate by taking out a lot of bass, and adding more treble (and possibly mids). Thoughts? My unboosted settings for II/+ style amps: Gain: whatever is comfortable with the pickups/player, but obviously a lot higher than with a boost. Around 8 though, usually. Low: 5 (the more gain you add to an amp, the more bass needs taking out) Mid: 2-3 High: 7 Res: 6 Pres: 8.5 The JVM is almost identical, but with mids around 4.
