Bought the tubemeister 20 deluxe yesterday. Over the Cab it sounded great, same as the peavey, but i am not sure if it was 18 or 20 watt. When checking the direct out on the HK I was totally disappointed. Only possible to set the eq at noon, everything else made it sound really bad. Together with the box i bouht the Yamaha thr100 hd. Thats a great box. If you want both, recording and live use its a great box worth a check! Over the cab the little peavy had a bit more bite or balls but when putting it to the DAW it totally creates great sounds!
