I'm still getting my equipment sorted out and could use a little advice. I just ordered a TC RH450 yesterday, got a good deal on it and the pedal from Zzounds and the pay as you go option just made it a no-brainer. I've wanted one of these ever since they came out so I'm excited about it. Now I have to figure out what speakers to match it to. I'm playing in a 3-piece blues band and use an Ibanez bass with flats on it for a quasi-old school sound. Currently I have an Ibanez Promethean P5110 combo running to a G-K 115MBE extension cab for 4 ohms. Both pieces are serviceable, but I'll probably sell the P5110 to free up some cash and I could sell the G-K as well. I like the TC cabs (RS210, 212) but they're a little pricey so I'm trying to figure out if I should keep the G-K 115 and just add the RS210 to it or if I should bite the bullet, sell it and go with the TC vertical stack. I know there are folks here with strong opinions on mixing cabs so I could just match the G-K cab I have. It was cheap -- $200 bucks at GC -- and they have an identical mate now for $169 so I could just go with 2 lightweight, cheap 15s, but I was playing through a MarkBass Traveler (210) yesterday and really like the sound of 10s, so I'm conflicted (hence the thread). So what do people think? I'm open to suggestions, but it's gotta be lightweight (no 410s in my future). I'm especially hoping to hear from other RH owners who have tried these heads with different cabs. Thanks for your time.
