I am having Jorg Schroeder build me 310L 4 ohm to replace my Avatar 2x10 and SWR Son Of Bertha . I am coming in to bit more cash with selling the LMII and getting a small bonus from work I would have about a $700 Budget . They LMII is 7 years old and I have the green lite from the wife to do the upgrade or should I just keep it I like it just fine but I am starting to feel it is getting and since I have the extra cash. The Heads are the usual suspects . 1 Augilar TM500 2 GK MB500 3 GK MB500 Fusion 4 Ashdown Root master 420 I play in Bluesy Power Trio but don't care for a very aggressive tone and play passive Fenders Jazz And P Basses with La Bella Flats . Or am just wasting my money and just keep the what I have Thanks in advance !
GK MB500 is clean and a little agressive sounding, also has B channel with light OD, so I don't think it will fit your style. For me, it works great and I love it.
I sold my LMII and got a Traynor SB500H; don't regret it at all. To me, much cleaner easier to dial in sound. It was funny, with one of my basses the LMII was killer. With the other, I just could never get it to sound good enough to take to a gig. Now all my basses sound good to me, but do have to tweak the eq for my passsive bass.
I use an Aguilar TH350 with a Schroeder Mini 12(angled baffle) and they match up well. Granted i could probably put much more power thru that cab. I'll bet the TH500 and Schroeder 310L would pair up real nice, especially if you like vintage warm and don't use tweeters or don't need hifi clickiness in your tone.
