    How do you feel about glitches, warbles, and artifacts?

    I've had a lot of fun with PLL fuzzes, comparator fuzzes, etc. But i build my own effects mostly, and explore a musical space that has, ah, selective appeal. Built a clone of a Death By Audio Robot. Fun but I am not sure what to do with it. Built a clone of a Clari-Not, with the fuzz mod for a...

    Strange Sheilding Question

    I'm sure it's been said but all shields must connect together and finally to ground. My friend Don recommends decoupling the signal ground from the shields (and the bridge/strings) with an 0.022uf capacitor paralleled with a 220k resistor. His main reason to do that is to provide some...

    4x8 vertical in-line cab. Good idea?

    I don't have the url handy but I've seen a roundup of frequency response curves for a number of different "cabinet simulator" filters that try to make a flat-response PA sound like any of various popular bass cabinets. Nearly all of them roll off around 3khz. On a 24-fret 4-string your highest...

    4x8 vertical in-line cab. Good idea?

    this one? "FaitalPRO 8FE200 8" Professional Midbass 8 Ohm" from www.parts-express.com! might work great. the PE website is great - most drivers, just scroll down to "optimum cabinet size" and it says how big it should be. Multiply by how many you are using. their support people can recommend a...

    4x8 vertical in-line cab. Good idea?

    For example i have a couple of this woofer which seems, although it has a foam surround, like the frequency response is excellent for bass guitar: Invalid Link Removed Four of them will need a vented enclosure with a volume of 3.16 cubic feet. This one might work well for bass too but will...

    4x8 vertical in-line cab. Good idea?

    I don't see why not but the dimensions of the box will be demanded by the characteristics of the driver.

    Advice on tiny monitors for bedroom desk

    The closer you put a sub to a reflective surface like a wall or a floor, or better yet on the floor near a corner, the louder it will be. Within reason of course, root mean square is still a thing. As for myself, I'm using the venerable e-mu 1616m and right now my monitors are a pair of old JVC...

    What's the deal with mixing driver sizes?

    I feel compelled to point out that the surface area of the driver is only one parameter among several which have to be combined to predict the performance of the driver. A long-throw 10, properly implemented may produce more and crisper bass than 12, 15, or 18" drivers. There's a fair bit of...

    Why Basswood Hate?

    I'm just pretty sure that tonewood isn't a thing on solid body guitars. Les Paul's whole concept was that the body should be completely dead and contribute nothing. First prototype was a length of iron train rail. Later he created "The Log" which you could think of as a neck-through design with...

    Should be an easy electronics question

    Replacing a pot on a pc board is only marginally more difficult than one with wire leads. If you were local to me i would tell you to bring it over. It does help to have some solder wick because a solder sucker doesn't always clear the through-holes. Assuming that there are through-holes. as a...

    Why Basswood Hate?

    does some wood glue and a tooth pick not work to remediate stripped screws in basswood? It works in the slabs of masonite some First Acts are made of . . . .

    Washburn AB-20 needs jack input replaced

    You probably don't need to replace it. It probably just needs to be cleaned. Deoxit D100 or D100L is what i recommend: https://www.amazon.com/CAIG-Laboratories-D100L-2DB-Electric-Cleaner/dp/B0002BBVN2/...

    Hum canceling in PJ configuration

    Very cool. I have a hard time believing that boutique pickups make as huge of a difference for guitars as people who have them say they do, and can't think of a reason why the vagueries and mojo in guitar pickups wouldn't matter a lot less on a bass. I bought my Corsair for $35 at a thrift...

    Speaker for a small ported 15

    Jazz Shielding Pictorial (Big Images Warning)

    Line the inside of the control route completely with the foil extending over the screw holes where the cover attaches. Line the inner side of the cover with foil as well.

    Hum canceling in PJ configuration

    I've done something similar. Though I should specify that it's not so much hum as buzz that i fight -- buzz from power conversion circuitry in CFL and LED replacement bulbs and tubes. Shielding the pickup route as best i could helped too. And of course the P route is copper lined too, and...

    Phase offset audibility, particularly with mixed cabs

    I've done some reading on the subject of arrays of speakers. My general understanding - what people who build line arrays and bessel arrays keep saying - is that there will be interference, but that at low frequencies the interference tends to have an additive effect. And in high frequencies...

    Speaker for a small ported 15

    the old Acoustic 136 was had a similar port. My gut feeling is that you'd treat it like a fairly short, very big port tube. I would count almost all of the tapered area as part of the enclosure rather than part of the port. The Delta 15A might work very well. Seems to want a vented cabinet of...

    Turning a guitar combo into a bass combo

    Yeah, there is always an awful lot of negativity when people bring up hands-on tinkering of most any kind on this forum. It's weird. My first thought when i saw the thread title was that, having gone over a lot of schematics, is that at least in the preamp section the major difference between...

    going from 8 ohms to 4 ohms without an extension cab..

    Tube (and very early "transistorized") amps have separate outputs for different cabinet impedances because they have transformer coupled outputs - and because with transformer coupled outputs the impedance of the load has a direct and meaningful impact on the behavior of the output stage...

    Behringer Bass V-AMP Pro - Part II: Get On Back, Jack, Do It Again...

    Refer to page 9 of the manual. "studio mode" (recording?) you probably want cab sim enabled, no? Looks like maybe you and i both want mode S3, since I'll be doing stereo XLR out to an Ashly MX-206 mixer, soon as my friend in ohio actually ships it to me. And I will be using PA amps and full...

    Behringer Bass V-AMP Pro - Part II: Get On Back, Jack, Do It Again...

    With a bunch of trepidation, i bought a BVP for $41 at ez-pawn. Missing compressor knob. FullCompass sells behringer replacement parts and i was ordering something from them anyway. They have the knob with a dot only, for $2.30. So i got that. Nothing wrong with it. Works just fine. Did a...

    Speaker upgrade in a Crate TB10 - stepping away from instrument speakers?

    So I went ahead and started this project anyway. Neglected to take a picture of the board. The TB10 (rated at 15w) has the venerable TDA2030 chip amp, transformer is marked +/-16vac which means they are using the 2030 right at it's recommended voltage. You find this chip in a LOT of practice...

    Speaker upgrade in a Crate TB10 - stepping away from instrument speakers?

    *shrug* that number is comparable to say the cheapest 8" bass guitar speaker offered by antique electronic supply, the Jensen Punch BP 8/150, at $81. Disabling the internal amplifier and installing a <$10 class-D module is probably not difficult. I would be very surprised if Crate spent $18...

    Speaker upgrade in a Crate TB10 - stepping away from instrument speakers?

    I'm just starting to learn to play. But i have been tinkering with electronics and especially audio electronics for 30 years. I've been successfully building and repairing electronics for at least 20. Board level, tubes and solid state. Got a bad habit of collecting speakers and headphones. So...
