1 Spot and Tech 21 Pedals

Chrisk-K · #1 10-14-2010, 01:58 PM

Does anyone know if the Tech 21 Bass VT can be powered with the 1 Spot? I don't see Tech 21 in 1 Spot's compatibility list.

If it is a 9V pedal, the answer is yes.

Tech 21 sells its own 9V DC adapter, so I think the 1 Spot will work.

Yes, I power mine with a 1 spot.

Works fine on mine.

me too.

I used a 1-spot with a BDDI, a Compacter and a Bass XXL at the same time, along with 3 other FX - no problems.

1 spot works on the vt and vt deluxe, plus about 5-6 other things i have plugged in.

Here's the deal regarding digital switching power supplies and our pedals. As stated in other posts many people use them without issue. However we have had reports of various noise issues with some of our pedals.

When you daisy chain effects pedals together with a digital switching power supply you will create ground loops which will sometimes cause noise . We really recommend using one of our power supplies our something like the Pedal Power that provides isolated outlets.

A digital switching power supply and has it's own internal oscillator. The oscillator has a clock as do analog chorus and delay pedals. Our VT Bass Deluxe pedal utilizes all analog circuitry for the signal path and has digital circuitry for the memory. Hence another oscillator. When you start to combine pedals that have internal clocks it's very important to use isolated power supplies. This is not to say that a DSPS won't work. Sometimes it will but in certain environments you may experience noise. This will be exacerbated if there is any gain producing device in the signal chain.

You can always just power our pedal with a battery if you feel there is some noise created by a power supply issue.

Mine has a bit of hum with the 1Spot, pretty much only notice it when I put the bass down and don't turn the pedal off. Not a big deal, but nice to know why it hums (besides that it doesn't know the words!) and how to fix it.

well i don't know why, but i've yet to get any noise whatsoever using a 1 spot on my vtd, vt or british, no matter what else i have plugged in.

Yea I have my VT daisy chained along with 4 other pedals, no noise issues. I used to do the same thing with a BDDI and even more pedals.

It's not that you can't use a DSPS, sometimes you will have no issues whatsoever. I use one at home in my office with a number of pedals and it works fine. On the flip side I was doing a musical theater gig in NYC a couple of years ago and was using a DSPS with a number of pedals. When I added an analog flanger pedal I started to get an incredible amount of RF. Not so when I switched to the battery and then the Pedal Power. Every time I went back to the DSPS the noise came back. In that particular scenario most people would assume the flanger was at fault. It wasn't and that's why we can't recommend using these types of power supplies with our products.

If it works for you that's fine. There are some electronic principles that can't be argued with though. Ground loops for instance.They introduce noise. Anyone that's ever plugged into more than one amp or plugged into another piece of grounded gear has probably experienced a ground loop hum. That's why DI boxes have isolation transformers that lift the ground.

So just keep in mind that if you are on a gig someday and you get a noise that you haven't had before the DSPS may be the culprit.

it's always good to follow good advice and i will certainly remember that! thanks!

I have used both standard and deluxe versions on a 1spot that also powers an analog delay, digital reverb, and a combination of other digital and analog pedals. I have never had any issues with hum using a 1spot. ever. The 1spot is always plugged into a Furman power strip with EMI and RFI filters, maybe that has something to do with why I've never experienced any issues with noisy daisy chains. I regularly rehearse in a garage storage place with known electrical instabilities that has interferred with my amp sometimes, but never my pedals.
