That sounds like a good call. They do that sometimes - my wife's just made a good call this morning "yeah, go ahead and buy it... I'll get you something else for Christmas..." what a doll! (Mind you, in return, I have just understood what an eternity/trilogy ring is and why it might be a necessary item... I'd never heard of the concept! I thought eternity rings were something that grannies wore because they'd, er, been around for an eternity...)
I seem to recall that the Deluxe hasn't been too bad for "reasonable" volumes - have I got that right? If that's the case, I'd suggest that, if "silent" practice really becomes a necessity, look at a Vox amplug thingy.
