    Simplest Cab Crossover

    Howdy all, I have a PA speaker that I've been using as a cab for many years with a 15" speaker and a tweeter/horn. For a reason that escapes me, I disconnected the tweeter a long time ago and the jack is wired directly to the speaker. Both speaker and tweeter are 8 ohms, and the amp I use has a...

    DC DMV Area Onboard Circuit Repair Recommendations -- Help Please!

    I have an instrument with a very complex onboard preamp circuit that needs some TLC. Does anyone have a recommendation for someone to tackle this in the DC DMV area? I'd really like to go with a well-vetted expert for this. It's vintage and has sentimental value, so I need to get this right the...

    Two pickup pole pieces buzz when i touch them

    Just wound my first set of pickups, so this is all part of the learning experience... Split coil for a P Bass. These two poles buzz when i touch them. None of the others do. (well, the two in between those two kinda sorta do, but extremely quietly.) - Should i be attaching the pole pieces to...

    Circuit mods I made to make my 3EQ Music Man sound more like a 2EQ

    I've had a 2004 USA-made Music Man SUB Sterling for a few years now. I never quite liked the sound of it as much as the 2EQ Stingray version of the same guitar, but I was never fortunate enough to find one when they were still affordable. Recently, I came across a Youtube video comparing the...

    The Biggest Problem with SG Basses solved- That Mudbucker is too damn muddy!!

    A little while back I bought an Epiphone SG bass. It was in quite a state, but was a good deal for a project bass and came with a hard-shell case. I had it shipped up from Florida. When it came the neck's scarf joint was cracked. The previous owner (who will be left unnamed) decided to "route" a...

    Player Plus Precision Passive Problem

    Hey All, I recently purchased a Fender Player Plus Precision with active electronics and 3-band EQ. The tone in active is stunning! I love the weight and pau ferro board. My only issue is that in passive mode, there is no tone control (no roll off, nothing). Now, I mostly use it in active...

    P Bass pickup on "PJ" setup sounds too muddy?

    Hi everyone. I seem to have an issue with one of my pickups and I'm not sure what's causing it: I recently finished building a PJ style Precision Bass. For the Precision pickup I'm using my old trusty Pure Vintage '58 and a Pure Vintage '74 (bridge) for the jazz pickup. Before this I had the '58...

    I really like the distortion sound of this 70s solid state from acoustic corp. Im looking for this tone in a pedal format. But what to look for? What type/category of fuzz is this? What circuit did they throw in there?

    PJ bass wiring questions

    Hello, I'm putting together a new PJ and am thinking about a different wiring scheme than my normal V/T/3-way switch. I've used this wiring because I've read it's the best way to make sure the P-bass pickup tone doesn't get changed by having the other pickup and different pots in the circuit...

    Is this pedal wired properly?

    Bassman 100

    I’m feeling like I missed something along the way here. Since when are Bassman amps actually used by bassists? All my life I’ve always heard the Bassman being regarded as a Holy Grail for guitar and total garbage for actually playing a bass through, much like the music master bass amp. Lately...
