I've got on the of the first runs of Koch Multitones with a Koch 2x12 extension cab and am really reluctant to sell it. However, needs must (as I need to somehow pay for the Axe-FX).....and nobody will buy it! It has one of the best drive channels I've ever used and a fabulous reverb. Really versatile and amp and heads turn wherever I've played it. One of the finest constructed amps (even though I've had to replace the footswitch jack and cable to a better one).Dolf Koch is a character all right.
His amps are indeed unique and opinions on them vary wildly. I'm not too fond of the ones I tried, although I used to play with a guy that had a Multitone that sounded pretty good on clean and rhythm. He never used the lead tone.
Hook amps are very good I've heard, but aren't they mostly Marshall clones? They look like that...
