Hi everyone, I am primarily an upright bassist, but recently most of my work has been through electric bass. In an effort to try and dial in my sound, I have owned about 10 bass guitars in the past 3-4 years. I'm down to owning 6 now. My two favorites, are a road worn jazz and Nash pb62 ( Though I usually love any fender usa or Mexican jazz or p bass). This is all to say my quest for the sound has been long, but with more emphasis on the instrument, less on the amp. Probably since that's alligns with the philosophy of upright bass, which is to get your desired sound out of your instrument first... wellll I feel silly to admit, but iv'e discovered recently though just how much the head is in coloring tone if not more so than the instrument itself for bass guitar. After already owning Aguilar, Markbass and GK rigs I've finally come to terms with the fact that I won't ever be fully satisfied without a tube head. I've considered some options. One especially being an Ashdown ABM600 since that is gear that Robin Mullarkey uses and I think around 500 watts is right for the gigs I do. (check him out he's great) Recently I bought an Apollo Twin X and got a couple plugins... one being the Ampeg svt 3 pro. I tried the other bass amp emulators too, eden wt800, Ampeg b15, Ampeg svt (which I also love) but I played through the svt 3 pro from 9pm until 5am in the morning with both my Jazz and P bass. That sound is what I want to represent on my live gigs, which range from small to large venues. I do a variety of genres and the svt 3 fits perfectly for me in being modern sounding enough for me and but fulfilling the low end with some real life and feeling. currently I own 2 mark bass heads A f500 and a mark bass little tube. I'm thinking of keeping one of those as back up and picking up a svt 3 pro. ( Was considering an svt 7, but reading reliability issues has scared me away.) My current rig sounds great, but I consider getting thee sound to my personal taste a top priority after 20 years of playing and never being getting the magic feeling I got when I plugged in to a vintage Ampeg flip top early in my career. The current Ampeg plug ins I am using, and the few times in my life I was able plug in to an Ampeg tube head (and maybe one Ashdown head) are the only way I recall not just being happy with my sound but also inspired. It also allowed me to play simpler bass parts. It allowed me to enjoy the role of just being a bassist even more than I already do! here's the thing, I only have 2 cabs a 110 Epifani and a 210 Epifani Dist. I love the dist 210 for it's weight and natural sound. I feel like the whole point of having Ampeg is for that low end and warmth though, so I'm obviously weary that my single 210 will "get me there". Do you think I will be happy running through my 210 with an svt 3 pro for small/medium size gigs, or should I plan on investing in different cabs as well? I worry about having to lug around heavy cabs but that sound has become an obsession and I won't be satisfied unless that sound is doing that thing. You know what I mean. Should I go with buying a new or used svt? Should I focus more on cabinets? Is there anyone else who switched from mark bass and why didn't you like it? Any bassists who prefers mark bass to Ampeg? Any advice, criticism, or insight would be appreciated. Thanks!
