When I tried out an AG700 a few weeks ago, comparing it to a Tone Hammer 500, I found the Deep switch to be voiced too high, more like a mid bass boost than a true Deep switch. I also felt the Q on the mid controls to be too narrow and somewhat unmusical.
I'll stick with my Tone Hammer 500.
I briefly owned a TH500 -- it had appealing qualities but, in the end, wasn't for me. The only other Aguilar amp I can recall playing is an AG500 -- this was in a recording studio, next to an old B-15 (my first time playing through one of those, too). Two very different amps in many repects (the old Ampeg and the AG), but especially in feel. The AG was hard, square-edged -- maybe a bit stiff -- but had a clarity and solidity that I felt the TH500 lacked (not trying to bag on the TH, only speaking relatively and to my taste). I thought I could like it in certain contexts (hard-hitting funk tunes, stuff with aggressive percussive techniques) but would need to explore it further. In my brief time with it, though, the high-midrange control seemed to me narrow and a little peaky -- this through an Aguilar 410 (I think a DB by the voicing -- and it was Tweed -- but I'm not sure). I was able to get a useable sound, but wasn't sure how easily I'd be able to dial it in for different sounds with different cabs.
The B-15 had its own, special magic, but that's a different amp, different story.
The AG700 looks like it might be more to my taste, generally, than the TH500, but I wonder how I'd like the EQ (and how similar it is to that of the AG500). I didn't spend much time with the AG500, so take anything I say about it with a grain of salt.
... I think some amps are better suited to certain cabs, which might color our opinion of them...
Yep.
The fan on the TH500 was a deal breaker for me, just too loud. Have you used the TH500? Is the AG700 quiter?
why do you need 500 watts? if the fan is too loud it would seem that you really don't need that much power. a fanless 50 watt amp would do
I sometimes practice late at night through the same pre+power rig (maybe minus one cab) I'll use at a loud club. Fan can be kind of annoying in that case (I know about headphones but don't like practicing through them if I can help it). Same if I practice through the little Kustom KXB500 I have (which has a loud fan -- at least as loud as the TH500's).
I've owned some nearly silent amps, too (Glock, Genzler, Eich), as far as fan noise goes. The fan noise isn't a deal-breaker for me, even practicing at home, but it's certainly nice -- and I notice the difference -- when it's not there.
I could see fan noise being an issue in certain quiet, intimate gigs or recording situations wherein a 50 Watt, fanless amp would suffice, but if you have an amp you like that you can use for the big stuff and the little stuff, why not? None of the "quiet" amps I mentioned seemed to have any problem staying cool, so it can be done.
Anyway, its importance will vary from person to person -- to each his own.
