I'm really not sure. Actually, I suggest you buy one used or new on E-bay as you'll find them substanially cheaper there than most places. Even better, if you can find an old used M88N, I usually find them better than the new M88TG. In fact, if you e-mail me, I know where there's an M88N listed for $220; assuming their list is up-to-date.
Well I try to visit whenI get a chance; though that's not much at all lately. Just been busy with the band's second album. Not nearly dne, but have been working on it.
By the way, if someone wants an M88N, e-mail me and I'll tell you whereyou can get one for $180!!! Given it's not already gone.
