I've read most of this thread and it appears that the majority of users are using the TH350 with 2- 8ohm cabs or 1- 4 ohm cab (350watts). I was wondering if any users have gigged or rehearsed using only half of the amps power, 175 watts @8ohms? And what were the results? Was wondering if the TH 350 would be for me, or save more $$ and spring for the TH 500? Thanks.
I gig the TH-350 regularly... Usually into either a pair of DB112NT's (combined impedance 4Ohms) or occasionally a Hartke 115XL (8 Ohms on its own) for small venues, and a couple of larger outdoor shows I've used the 115XL with a 210XL on top (combined impedance 4Ohms).
I play in a 3 piece funk/Rock/jazz trio, keys, bass, kit. And I also play in a 4 piece alternative rock band.
Gigs I find no problems with volume into 4 Ohms, two cabs...
When rehearsing I mainly use one 112NT or the 115XL... This is where the TH-500 would come in handy, occasionally I feel the need for a little more power at 8 Ohms as rehearsals can get loud... A single 112 can get lost but the 115XL cab is more sensitive and have more surface area and is quite obviously a louder cab @ 175w, holds its own with the TH-350.
Be aware min impedance of the TH amps is 4 Ohms, not 2...
So it's a combination of your volume requirements, cabs, room acoustics and budget, but I am kicking myself a little for not going the TH-500, it was budget at the time, but now I'm seriously looking at getting the TH-500 for single cab 8 Ohm situations.
