My only concern for you in this post is to attempt to give you some assurance that TC Electronics is good gear. I'm aware of pros that use it and love it. The RH450 is the one that I use. KJung's descriptions of its tone are spot on. To me, it's voiced perfectly. There are other reasons to consider TCE, by the way:
- It has a built in tuner
- It has a built in compressor that is very usable
- It has built in dirt (subtle to very growly) in the tube tone (should you get the RH450)
- The DI is dead quiet (note the TH500 is as well)
- It has memories that store settings so the knobs moving in your gig bag matter not (should you get the RH450)
- It also has a tweeter tone that emulates the pot on the back of your cab (should you get the RH750)
So to me, it's everything you need in one box with outstanding tone.
I will tell you that the opinions on this board that were so strongly against TC Electronics gear that they actually lead me to sell my first RH450 and venture down the rabbit hole of buying and selling amps (I figured people knew much better than me). I went to the Aguilar TH500, the Genz Benz Shuttle 6.2 and finally I came back to the RH450 and realized it was my ears that matter vs pleasing the TalkBass monster.
I will say that if you land on the Aguilar TH500, you can't go wrong there either - awesome amp.
Take it for what it's worth - I'm not a pro - I play in Church. I value convenience (integration) and I look for a supportive tone that cuts through. RH450 has it in spades.
