When I say trade, what I literally mean is taking the OR15 back to the store for a full refund as its under a month old. then getting a th30 with the refund. maybe using the DT as trade in to pay the difference (if I think the TH30 is probably going to do exactly the same job).
The more pertinent question i suppose should be: Is the Dark Terror preamp the same as the TH30 dirty channel preamp? because if it is, to my ears its probably going to sound exactly the same.
I think I'm going to take the OR15 back to to the store whatever happens so it's really a DT vs Dirty TH30 shootout. Take literal value of the items out of the argument.
From what I've read, the Thunder 30 has the dirty preamp from the Rockerverb, only with the shape control from the Thunderverb. I happen to have both schematics of the Rockerverb, and the Dark terror.....same preamp except for the tone stack. So, putting the puzzle together answers that. For what the TH30 is supposed to be, it's a good sounding amp. And for what it's worth, the clean channel is based of the Rockerverb MKl clean channel, so I've read. It's a hybrid Rockerverb/Thunderverb, made in China.
