Is the TH 350 a solid head that can be pushed?
What? There are virtually NO problem posts on the TH line of amps at all. Where did you hear this? The TH500/350 is ROCK solid. You might be confusing this head with the Ampeg 500 watt class D amp, which continues to have problems.
Whether you dig the tone or not is anyone's guess. I love the big low end (meaning very round and punchy), the very present midrange (easy to control with the powerful semi-parametric mid control) the very nice DI, the good wump of power (even with the 350), and the stellar reliability of the head based on virtually no failure reports or even safety shutdowns. I think someone had a big dump/spike of power that blew out a DI and was quickly fixed, but that is about it.
Anyway, impressive head that can keep up with most of the 500 watt models out there. The gain control has a lot of tonality to it, and the drive control is a nice control for tightening up the tone and adding a bit of feel.
If you run your all tube amp very clean, and crank the bass and treble for that super deep, scooped, sweet extended top end sort of thing, this amp might not be for you. If you like it growly and punchy, and 'not sizzly' up top, it is amazing. Amp seems to be MADE for a P Bass or a 60's J with nickelwounds.
IMO and IME.
Edit: One thing to be aware of. If you are really cranking the TH350 and using an 8ohm cab, you will see the 'clip light' come on. The clip light on the Aguilar is not the 'typical' input gain overload indication, but rather an indication of the overall preamp being driven hard. It is 'post master volume/pre power amp'. So, if you see that come on, it does NOT mean you are running out of headroom or that you need to turn down. It just says that the preamp is hitting the point where it is adding some additional 'grit' to the tone, which sounds good to many. That is the primary difference between the TH350 and TH500... a bit more output of the power amp at given preamp settings that results in you having a bit more clean headroom. Otherwise, they sound identical, minus a couple features on the 350... the second speakon out, and the effects loop.
