I recently bought this portable Bass Head TX 300 for a cabinet of 300 watt. The sound is good and very distinct. The EQ. Compressor and Gain are giving enough to figure out a specific and great sound for my Fender Jazz Bass. The lowest B is very distinct. I was planning to buy the TX 600 which is better but I was afraid to overpower the Cab 300 watt. What watts is good for a cab 300? Anyway, I am satisfied with it and my cab which is a very light one. I tried also the Hartke 112 with it and completely satisfied but I am not a very slapping bassist. I am encouraging everyone to get any of them. Good luck!
