That is the only thing in the chain besides the bass and the preamp. The high end would have been over the top if I had not used a speaker sim.Recording:American Fender P > Focusrite 6i6 instrument input > Ableton**so I could make loops of bass riffs to play backPlayback:6i6 line out > reamp box > My bass preamp > 6i6 line inMixdown:Ableton > NadIR cab sim (I forget which specific IR file)

Josh Maxwell has used this preamp with guitar and synths. Phone recordings but you can get an idea of what he is accomplishing:https://www.instagram.com/thatwithtusks/He gets a very nice clean tone from a baritone guitar > preamp > reverb. I was also really surprised by the Forktie stuff and the sounds Aarne got (link to recordings in the OP).The gain sound that makes the TS unique is the whole reason I built this preamp. I just wanted to inject more low end to those awesome upper harmonics so I started the EQ at 20hz on this version. I also added a double gyrator on the 500hz so you could get that "modern" scoop that makes the SVT Deep switch so useful. As more people start to use these and record with them, I hope to be surprised by what they come up with

Just to add this to the thread, Tommy(and, maybe, free meat) seem to already be owners and fans.Tommy wrote:free meat wrote:Pulled the trigger on one of these modded ts-120b clones.I bought the last one of these. Sounds awesome. Actually sounds really great run into the front end of a guitar amp as well -- if you totally cut the 20Hz, 50Hz and 5k bands.I might be looking to sell my Rusty Box.

Hey Tommy, I appreciate any and all feedback!1) EQ bypass - because it potentially has three functions. a) as a comparison to see if I improving my tone with how I have my EQ set. b) an alternate boost. c) noise reduction by taking it out.-This is definitely a good idea. I doubt you would get much noise reduction from bypassing the EQ, since it runs at unity gain and has fairly high headroom (34vdc) but I wouldnt mind doing this in future iterations for the other 2 benefits you mentioned. Plus, we can test the noise reduction to see if you are correct 2) XLR out snap/clip. What was the reason you left out the part that lets the cable to snap in?The XLR inputs I bought did not come with an outside clip. They do lock, though. Just no tab thingie on the outside. If thats a real issue, I can replace it for you with one with a tab.3) My 1978 seems to have some instant/constant noise (ground?) when you click the boost on, even with the gain all the way down. BUT I haven't tracked this down yet to see if it is a fault of bad ground at the outlet/amp/etc.If you want to send it back, I can take a look! I havent heard this one before so there might be an actual problem going on. I will split the shipping with you (we both pay for our own shipping) if you like. **EDIT** actually, you are in Logan Square, right? I can take a look anytime this weekend! I am in Toronto this week for work but I get back on Friday.

I am in Toronto this week for work but I get back on Friday.Thanks Jason!Hmmm, mine doesn't seem to lock, let me try a different cable. Maybe it's the Neutrik connectors on my balanced cable.No rush! I just moved this weekend so my life is kind of a mess. I do want to try it with another amp (and in this new space) to see if the issue follows. I also didn't check if it is only an issue when the footswitch is plugged in vs not. I only remember that it goes away when I click it off at the pot.Yep, could be a mis-match on the XLR cable or it could just be a bad jack. I can replace it, either way. PM me your number and I can meet up with you this weekend, if that works for you. Totally understand how moving can throw things into kind of a tizzy and you might need some time to just stare at all your stuff and figure out what goes where

so, I ordered one. can't wait to test it.I will need some sort of poweramp as I want to turn this into my live rig.can I get a PA poweramp or should I look into specific bass amps.I checked out Crown and QSC amps so far. it should be rack mountable, light and not too expensive. 2 x 300 Watts should be fine. I have a Mesa 1x12 and a GK 1x15 speaker that I'd like to use, both rated 300 watts.

I think they can be had for pretty cheap, mine was $50 at Music Go Round just a year or two ago. 300w @ 2 ohms, 210w @ 4 ohms.Totally. I would expect you could even get old CS-800s pretty cheap, albeit not $50 cheap. One of the bridged into a cab would be killer loud and full. As with all Peavey power amps of that era, built in limiter.
