Is the AC adapter center pin negative and the barrel positive? I want to use a 9V power supply for BOSS pedals.

i don't know. this amp was such a disappointment that i shoved it on the back shelf and never use it. it was so overpriced.

I only use batteries, but the marking would appear to be so. AS far as the other answer: Sorry 'bout that. It is, after all, just a "rehearsal amp", as the seller said, not a full-blown concert amp. I use it for a harmonica amp at a nursing home; it works just fine for me!!! I can't haul around anything bigger.

Unfortunately, no. I've been using Boss 9v adapters with my Joyo pedals, and so far no trouble with the AC Tone, the American Sound, or the Crunch Distortion. Joyo does make a multi-strip power supply, but I don't like the pricing on that one when I already have my Boss wall warts. Also, I continue to think these pedals work better to color your tone going into an amp than they do directly into a sound board or recorder. Some of the YouTube direct-in samples sound more like a live amp than I've been able to achieve with my setup. Maybe I'm just spoiled on the tube tone I'm getting from my rig. Unfortunately, no.

It's actually the DC output to the device from the AC adapter that you want. It is 5V at 600mA. The plug-in tip polarity is positive inside, negative outside.

Your best bet would be to find one with the correct specs, I have a bp200 and only the correct power adapter would allow the pedal to function correctly

On the side of the unit, it says "7-9 Volt", and a diagram for NEGATIVE CENTER. This is important because most wall adapters are positive-center, and using the wrong one might burn out the machine (unless the circuit designers went the extra mile to protect against that, which I'm not going to try to find out).

They are just different ways of connecting, one by screw block and one from a power adapter plug. It depends on what you are going to power it from. The negative screw block terminal is very useful as well to connect the grounds of the source signals and the power adapter so you have a common ground.

You have to look near socket on device, or on original AC Adapter. On the Velleman PS, it's clear how to connect adapters for center positive, etc.

The center pin is negative and the outer rim is positive. Most DC power supplies are center-negative, but a few are center-positive so check the supply before you plug it in. There will be a diagram on the power supply telling you which configuration it is.

The photo is wrong. I think they just used a generic photo and didn't think to blur out the polarity as well as the output voltage and current. The polarity of the adapter is actually "negative polarity". The output voltage and current is listed as 8V - 10V; 1A - 2A. This is a pretty big range, and I think it is causing the adapter to work for some people and not work for others. Mine works with my PT-1090.

Usually the center connector is Positive. Use your DMM to determine the polarity.

Center-tip-negative polarity is not the norm, easier to buy one here. You'll see one in the "customers...also bought" links--e.g. Planet Waves 9V Power Adapter, which has the polarity you need. Just make sure any adapter you use is "center tip negative".

Any standard 9 volt pedal power supply will work. The OneSpot works well. The key is that pedals use a negative center connector. That means the center part of the connector is negative and the outer ring it positive.

I use a generic one, with interchangeable connection pins and variable voltage (but fixed 3A). Set it to 9V, center pin positive connection, and you're ready to go. I'm pretty sure you can find one here.

With a standard 12v DC adapter. Look on the PCB and you will see a + and - sign indicating the polarity.

No. Only the tip-negative and tip-positive (black and red) are included. I made my own 3.5mm connector for an old DOD EQ, but haven't yet had a need for a 9V connector. If you have a spare 9V connector with pigtails (or can cannibalize one from some junk), then you can roll your own. Otherwise, the 9V cable shouldn't be too expensive.From BBE's website:Features includeUniversal Power SupplyEight isolated, regulated and filtered outputsIncluded Cable Set consists of:8-2.1mm (Boss-type) black cables2-2.5mm red cables reversed polarity (Line 6 type)Supports 9, 12 and 16 voltages No. Only the tip-negative and tip-positive (black and red) are included.

When I first installed mine I had the Positive and Negative switched on the small two pin connectors for the case. This was the problem for me. Once I had the correct +/- everything worked fine.

The center post is NEGATIVE, the outer shell is POSITIVE. This is opposite of what many common connectors for power supplies have. You need to look on the Casio specifications for the AD-5. Also, there is a small diagram on the plastic case of my CT-700, where the AD-5 plugs into the keyboard, that shows this polarity requirement. Jay Daugherty is incorrect.
