I've been acquiring random bass & guitar effects pedals for a while, basically buying up anything interesting that I find being sold cheap second hand. I've played around with various different combos, but I'm interested to hear what other people would do with this. So treat this like a box of lego - what are you gonna build? And what's it gonna sound like? Bonus points if you can point me to a recording of the kind of sound you're aiming for. You can also add in one or two missing pedals if you think there are others I should be adding into the mix here. Pedals include: Sansamp BDDI MXR blow torch fuzz/overdrive (NOT PICTURED) EHX bass big muff Boss ODB-3 bass overdrive MXR sub octave bass fuzz MXR blue box octave fuzz EHX octave multiplexer Boss OC-3 super octave 'Dumble' homemade overdrive* TC Electronics skysurfer reverb MXR smart gate Neewer noise gate Marshall ED1 compressor (*Seller's description of the Dumble: Based on the NE5532 chip. Can go from full distortion to light overdrive with the drive knob. Has a smooth sound that works with single coils and humbuckers. Mid-focused overdrive tone.)

Thanks everyone, good sleuthing!

Would love it if someone can tell me anything about this bass, or have a guess at who made it and when. Here's what I know... neck thru double truss rod active serial number 00134 Bonus points if you can tell me what's going on in that last photo, I've never seen electronics like that (but also don't know much about active electronics). What's the rectangular thing and is meant to look that lumpy?

This is an update on my previous post: I had a go at rewiring the bass, and it mainly works ok. But there's a problem with the volume knob - first, it doesn't actually control the volume at all, and second there's a buzzing noise when I touch it. The buzzing suggests a grounding issue but I don't know what... Can anyone help me figure out what's causing the problem? I more or less followed the wiring diagram below, except for a couple of changes to make the rewiring simpler. Do either of the changes below sound like they would cause the problems with the volume knob? 1. The original wiring had everything grounded to tone, so I left it like that (instead of unsoldering all of those ground wires and resoldering to volume) 2. The tone pot was wired completely differently and I kept it pretty much as is: volume wire goes to the left lug (instead of the middle lug, like in the diagram) left lug also connects to middle lug capacitor is on the middle lug (instead of the right lug, like in the diagram) and then grounded to the top of the pot right lug grounded to the top of the pot

Thank you to everyone above for your help! But now comes the follow-up question, where I try to understand what I've done wrong and how to fix it... EDIT: Removed the rest of this comment and moved it to a new thread here:

Thanks, but I want to give this a go myself. I make a complete hash of it then good to know I have a backup option!

Is this about the new blend pot somehow being consistent with the volume & tone pots? Or just about upgrading the other pots since I'll have them out anyway? I hadn't planned on that... but will think about it if it makes a noticeable difference. Great tip!

That's mostly just me holding the bundle of wires out of the way to take a clearer photo. But a few of the black wires go into the body to connect to the pickups - as I've since learnt, these are extra grounding wires.

Before I get to my main question - what is the point of 2 separate volume knobs rather than a blend knob? It really annoys me that I can't quickly & easily adjust volume without impacting on the tone, or vice versa. I can't really see any advantage of double volume knobs but it's so common... what am I missing? Ok, and now the main bit. The plan is to turn the 1st pot into master volume and replace the 2nd with a blend. But I'm kind of confused by the wiring under the hood, and it doesn't seem to match what I'm seeing in the diagram... . Based on that, I was expecting to see three wires connected to the 1st pot (two from the pickup, and one going to the 2nd pot). But instead I have one from the front pickup (yellow in the photo below), one going to the jack (white), and one to the 2nd pot (white/red). The front pickup also has another two other wires (both black), one going to the 2nd pot and one going to the tone knob. Does anyone know why the wiring seems so different to the diagram? Or am I missing something obvious here? And any advice on how to approach the rewiring? Thanks!

Actually, I just took another look and I don't think that's the same bass. This one has a humbucker but the ones in that catalogue (and the reverb link) have split pickups.

Good sleuthing, thanks!

It's not very helpful in this case...

Does anyone have any idea what model this might be?? Looks similar to the B-10 but I can't find anything online about a single pickup model.
