Most probable cause is low battery or defective power convertor if battery is not used.

No sound


This is not a powered mixer and so you must connect a power amp to the "line level" outputs of the mixer. Other "no output" problems could be related to buss assignments and other signal routing issues. Check for output by connecting "Main Out" left or right to a guitar amp input instead BUT turn all volumes down to zero before conductiong this test as guitar amps are designed for "Microphone" level inputs. Owners and Hookup manuals can be found here...

Input and/or Output for pedals not passing sound through


I will answer this assuming you have connected the inputs and outputs of both the pedals AND the amplifier/guitar properly. Double-check your connections! ;)

Otherwise...Have you checked all the patch cables to make sure they're ALL working properly? That's usually the culprit in a situation like this, all other things being equal. Cables take the majority of abuse in your signal chain and also happen to be the weak link in the signal chain as well. It only takes one bad patch cable in a series to interrupt the signal.

I would take a pedal with perfectly functioning inputs and outputs and use it to test each cable yer using. If you verify all the cables are in fact working properly (and you are 100% certain everything is connected correctly), that indicates there might be an issue with the pedalboard's onboard electronics. At the most simple, the "From Guitar" or the "To Pedal" or the "To Amplifier Input" jack might be bad. One or more them, in fact, but it only takes one to entirely interrupt that signal chain. The loop section is less straight-forward in that if one of the loops has a bad input or output jack, that shouldn't affect the overall signal chain, nor the inclusion of the other pedals in said signal chain.

So, I think it's one of three things:

1. The pedals, guitar, or amplifier are not properly connected;
2. You have a bad patch cable;
3. Something has gone wrong with the electronics onboard the pedalboard, and this will probably require service.

Hope that helps.

Danelectro Hodad Mini Guitar Amplifier - no sound output


Do the cables have the right length plug/jack ends? There are 5 different lengths in use. Some will short the inputs completely.

Do you get noise floor from the amp when turned full volume? if so, it is an input/mute issue. The switches these days are rather cheaply made and prone to dirt or corrosion. Try cycling the switches repeatedly. The same with the jacks.

If there is no warranty left- pull the chassis out and under a regular flourescent light, noise test each part of the amp with an insulated screwdriver- just make a contact on discrete transistors, or on the inputs of the IC's and work back towards the input. If it is clean all the way back-it has to be the cable, cable ends or the guitar.

The half-way cord is the clue. Read up on unbalanced and balanced lines and TRS connectors.
One of these requires TRS connections and the signal is being carried on the RING of the TIP-RING-SLEEVE connector. Plugging in half-way the TIP touches the ring pickup contact. The emgs one MAY use TRS type cables and there may be a reason the signal and hot of these are reversed. If I could find schematics on all this equipment I could unravel the exact cause. You could make an adapter with a Stereo 1/4 inch plug and a 1/4 inch jack by wiring it to swap the tip and ring between them to use for connecting to the emgs guitar. ALSO verify you are using the SAME type guitar cable for both.OFTEN a TRS cable will NOT turn on the electronics when plugged into a guitar. Use an unbalanced instrument cable unless you have the XLR type output. Use of an adapter from the XLR type cable into the Boss will usually not work.

It is happening because you have a ground loop. You need to check the ground on your amp. If it is an old one that does NOT have a three wire cord, you need to have that changed. Failure to do so could also damage the interface. ALL your equipment, computer and guitar am should be powered from the same receptacle. If you have other devices connected to your laptip such as printer, they too MUST connect to the same receptacle or plug strip. Any phone lines should be disconnected from the laptop. Make sure everything has three wire cords. The interface probably sends out line level, so you should use a low gain input of the amp and use very little gain as the interface probably has 20 or more Db output than a guitar.

If you touch the area where the input and output level bars are (lower right of the screen) it will open a page called "Input Options".
Make sure the input and output gains are up about 75%. Usually the output gain is about 5-10% lower. If you're getting a button that says "No Input" where the input/output level bars should be on the lower right corner, it is telling you that your iPhone headphone/mic jack is not sensing the line from the Amplink. Leave everything connected, and exit the Ampkit program and then start it again. It should reopen with the level indicators showing. These connections are all finicky.

I get no sound at all when I plug in to the input and its not my lead or guitar, how can I fix the amp?


This is probably not a DIY repair. You best take it to a repair shop. Likely the power amp has failed or other common problems are broken connectors/jacks, broken volume pots, and finally circuit board cracks.

Static Noise from guitar amp.


I take it you have made sure that both the cable to the distortion box from the guitar and the cable to the amp are both good. From the description you give, it sounds like there is no signal getting to the pedal. If the cable is good, then the next likely suspect would be the input jack on the fuzz box. Try wiggling it a little with the guitar cable in place to see if it is loose. Some input jacks are unbelievably cheap and flimsy. A crackling sound (static like) is almost always a bad connection. If it was the output jack, I would think that the guitar signal would come through a least a little bit, but you might want to try wiggling that one, too, if the input jack isn't the culprit.

Another possibility to check is the battery, but this doesn't seem as likely. Some effects units devour batteries, especially units that use 9V batteries. I have a multi effect pedal that kills a 9V in about an hour.
