![]() ![]() You could bring me a BelAZ 75710 (the absolute largest AFAIK of the “haul truck” vehicles, those special extra-huge dump trucks for massive coal mining operations)… heck, you could bring me a frigging fleet of them, it wouldn’t matter, I still couldn’t carry a tune in ’em all. That’s one that’s intrigued me for a *very* long time… mind you, *any* attempt by me at any sort of musicality ends rapidly in severe auditory pain to any bystanders within earshot… you’ve heard the phrase, “couldn’t carry a tune in a bucket”…? LOL. ![]() Number 2 is also better because the metal strip holds up to playing a lot better than the plastic, and you can tension it so it gives you a well defined contact point. Option 2 is more difficult to measure, but it gets rid of the hum entirely. Option 1 gives you a simpler way to read the strip as a resistor divider but it doesn’t completely remove the issue. This still gives a capacitance path through the insulation so you still get a tiny bit of modulation and hum, or 2) invert the whole thing and put a grounded metal ribbon on top – preferably still insulated on the top side. The solution to that problem is to 1) insulate the ribbon from the top. Either way, the point where you touch the ribbon becomes a path for these currents and it sums up to the currents that go through the ribbon. If the whole thing runs on batteries, it doesn’t matter, but as soon as you plug into an amp your oscillator goes bonkers because the ground lead gives you a path for all the currents that you are picking up from the environment, or maybe there’s some voltages in the ground wire and you’re conducting them to the floor or something. The difficulty is that when you touch the ribbon, you get a rather strong AC hum from your fingers and it tends to mess up with any voltage measurement.

The rest of the ribbon controller is a sandwich of thin copper plates and non-conductive plastic mounted on a wood base.īut what’s a fun controller without a fun instrument to control? As a special bonus, made a little square wave-squirting synth based on the 4046 hex inverter and included the schematic for it. Here the wiper is made from Velostat, a fun, low-cost conductive material that’s also pressure-sensitive. While it would definitely be an interesting exercise to make your own standard twist-style potentiometer, shows that making a ribbon controller is relatively easy.Ī ribbon controller is essentially a deconstructed potentiometer that uses your finger to actuate the wiper. Synthesizers of all stripes are often controlled with various types of potentiometers. Whenever you’re ready to have some next-level fun, try making controllers for your DIY instruments. And besides, noise plus rhythm equals music. Even if it’s a straight-up noisemaker, that’s noise you can be proud of. In short, the Electro Harmonix Bass Micro Synthesizer is a unique effect pedal for adventurous bass players.There’s kind of a special joy in making instruments, no matter how simple or complex they are. Your bass tones provide the input that the pedal processes, producing analogue synthesizer sounds with rhythmic patterns or reversed bent sounds. The Bass Micro Synth is capable of simulating synthesizer sounds. Get creative, and you might just discover the secrets of legends such as Bootsy Collins, who use this pedal live on stage. The ten filter faders of the Bass Micro Synth allow you to generate a wide range of sounds. ![]() It's hard to describe a pedal such as this in mere words - you should really just give it a go. How does the Electro Harmonix Bass Micro Synth work? Offering infinite possibilities, unique sounds and plenty of functions, this pedal is a real must-have for innovative bass players. Its four voices - Guitar, Octave, Sub-Octave and Square Wave - can be adjusted independently. The Electro Harmonix Bass Micro Synthesizer provides you with a budget-friendly way of producing the most popular analogue synthesizer sounds. ![]()
