TH350 to 500 Upgrade Question
My current rig, which I love, is a TH350 with an SL112 and, for big shows, a DB115. When I'm really pushing it, like on outdoor shows, the TH350 holds up but distorts quite a bit. Am I right in thinking that upping to the TH500 would give me more headroom and clean power if I need it?

Not necessarily while using the same single cabs. Try using two cabs instead of one, unless you did the "most power from the amp thing" with 4 ohm cabs. Two cabs will be much louder than one cab with quadruple the raw amp wattage.

Sorry, just to be clearer, I do use both cabs in the larger outdoor shows. I still have to push the TH pretty hard and it does distort. Would the TH500 help?

It might, it's will only be another 150 watts from 350. Maybe time to double up on the most efficient cab (probably the 115) or better get a big cab for your outside gigs.

Where is your gain knob set? Higher gain settings push the distortion.

I had the same problem at a gig last week with my TH-350, and had the same thoughts...
Edit: oops hit send before I finished my post... Anyway, I also was a little concerned that I made a huge mistake not going for the 500, just didn't have the extra cash and needed the amp.
Back to the gig, I think I might have pushed the gain too hard without really cranking the master enough, so waiting to play at the same venue, this time trying a different gain structure...

@B-String: Is the efficiency the same as sensitivity? The SL112 is 99db, whereas the DB is 96.
@Rick: I keep the gain at about 9 or 10 o'clock, without that the tone doesn't really have the meatiness I like.

A pair of like cabs will pound harder than a pair of dissimilar cabs.....time alignmnent and comb filtering. At a difference of 75 watts when running at 8ohms with a single cab...prob not much of a noticeable difference....so if you run a single cab most of the time...a TH500 prob won't help you IMO. If you run 2 cabs more often, then yes....the extra juice will help. However, even with he extra juice your still fighting against time alignment and comb filtering effects between the two dissimilar cabs. If it were my $$, I would sell the 112 or 115 and buy a sister cab for the left over speaker. Due to size and weight, I'd sell the 115 and get another 112. I'd try that 1st. If that doesn't get you there, sell the 350 and get the 500.

Yes, 96 db at 1 watt is pretty weak for a 115 so double your 112.
