I need an amp footswitch wiring diagram... Ibanez TB100H

[subanots]

I just bought one of these, and it didnt come with the footswitch. (Its a Toneblaster 100 H)
View attachment 54102
I have looked everywhere and I cant find the wiring diagram that I need.
This is what the pedal looks like:
View attachment 54104
Its connected by two stereo cables on the back of the amp. TRS
Can someone help me here? If you have one can you send me a picture of the inside?
Or, even better, if you know what the diagram looks like can you post a pic of what it should be?
I have a few amp pedals and none of them work on this amp correctly...

Thanks.

This amp is pretty fun! Sounds good. I got it for SUPER cheap at a local pawn shop. They were tired of having it in their store. Sold it for 80% off the asking price.

Should be really easy actually. I'll be back with a diagram.

Your biggest challenge will be finding an enclosure big enough for 4 switches (even a hammond 1590DD could be a bit small). You could, however, divide it in two smaller footswitches (one for each cable) or, if you can do without a switch or two, make it smaller.

Here you go.

couple of things:

1- To short either tip or sleeve to the ring, use an alligator clip or something of that sort. Just listen to what is activated when you do so to understand which zone activates which function.
2- I illustrated DPDT switches as I use these but you can also use SPDTs (or even SPSTs) if you have them or if they are more easily obtained where you are.
3- This is as simple as I could go. This LED in series way of doing it should work as the drop in voltage shouldn't be problematic with the function switching. If it doesn't work properly, PM me and we'll move on to the next best thing. In this diagram, all the switch does is complete or break the circuit allowing current to flow through the LED. Completing the circuit activates the function. In some cases, this may be reversed (depends on the amp). What I mean is that, for the reverb (example), the led could be light-up when the effect is off. If this is the case, you can either choose to omit the led or use an external power-source while using the second pole of the switch to take care of the LED (I'll help you again if it gets to this).
4-I included a little diagram to help you identify the zones on the TRS male connector... might not be needed but it was quick and easy to do.

PM me if you have questions.

cheers

Thank you so much. I will let you know how it turns out. You rock! :bigok:

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

No problem! As I said, this is as simple as it gets. If it doesn't work due to the voltage drop across the led there's another way to do it... just double check everything thoroughly before you report failure though

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

Im probably going to nix the led's. Dont need em. I will also just split that in half. I really only need a switch for the channels. Maybe the boost will be nice to have, but I rarely use it. The mid and reverb switch wont ever get used, either.

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

In that case, if you only want 1 switch, go for a 1590A enclosure... you'll save a lot of space.
For 2 switches use a 1590b sideways... dead small again for 2 switches...

Do you need me to redraw the diagram withou the leds? All you need to do is take the black wire(s) and send them straight to the top lug of the switches instead of going to the led's negative leg...

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

there's a switch for mids??

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

I'll have to check the manual (or I won't...) but it's labeled "mids shift" so I'm expecting some kind of pre-defined (or user-defined) mid boost or scoop....

I wired this up like the diagram, minus the led. When I plugged it in, with a trs cable, it didnt do anything. The purple wire was going to the top lug, which I believe is the sleeve, and the blue went to the middle lug... (ring, right?)
I tried a bunch of different combos, and nothing happened. I was just going to try one switch, to see if it worked. I found a housing that will take three switches. Isnt that a stereo jack, and a dpdt switch? What did I do wrong? Thanks in advance, be gentle....:headache: you can just use ms paint and draw over this photo if its easier.

I'm really not familiar with Cliff-type jacks like this (but I really should be, I'll be using them in my amp build).

It would look ok at first sight. It's a basic connection.

Did you first try to take the jack plugged in the amp and not to the footswitch and short the ring to either tip or sleeve and listen to hear if any function is switched on?

Also, you may have to look for your user's manual. As with any amp, yours must have a way to switch the channels and functions manually right? Usually, amps will have to have to switches in a particular position for the footswitch to work. For example, my Orange Rocker 30 needs to be set manually on the dirty channel for the footswitch to work. If set on the cleann channel, the FS has no effect...

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

i tried shorting the ring and tip, in both footswitch plugs. There are two on the back of the amp. From what I found the manual says that you need two trs cables going from the back of the amp to the footswitch. So, I plugged a cable into one and used alligator clips to try and short out the other end of the cable. Nothing changed in the amp. I dont know why this isnt working, it seems so simple. Maybe the jacks are messed up on the amp? I can use the trs cable with a Boss fs6 and plug it into a Roland and it works....

just read this:
The plugs at the end of the included foot switch cable are numbered 1 and 2.Connect the plug marked 1 to the rear panel FOOT SWITCH 1 jack, and the plug marked 2 to the FOOT SWITCH 2 jack. You can use the foot switch to turnthe Boost switch on/off, to switch channels, and to switch Mid Shift and Reverb on/off.Caution: When using the foot switch, you must connect both plugs. If the footswitch is connected, the corresponding switches of the front panel will not function

I think I have some more tinkering...

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

that was it, I needed to plug a cable into both footswitch imputs, the alligator clip trick is working. Now I can finish this thing. Thanks dude!

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

so, the left side of that jack didnt work? I had to use the lugs on the other (right) side and it works.

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

Excellent!!! Reading the manual, although not very manly, usually yields good info to help us along the way....

I'm not sure why one side of the jack doesn't work, it may be burnt from too muh heat during the soldering process or it could be something else entierly.

Are all three of hour switches working now?

Congrats on having some (i not all) working at this point. The worst is done and you've laready learned a little more!

Btw: sorry if I take long to reply, it's a nice long week-end and I play outside with my daughter a lot... I'm still checking this when i get a chance and we'll get you through this

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

now worries. You were getting back to me in good time. Yeah, everything is working. I will post a pick of the temporary pedal (I want to get a smaller housing)
I had an old Digitech pedal, I think it was for a looper, or something... I cant remember where I got it.
I might wire up switches for the other two spots. Note the switch in the back. (its for the gain, I figured I wouldnt use it that much)
I may wire the "mid" switch to the switch in the back and put the other three in the existing spots on the top.
I should re-paint it into something cool though... First I need to get more foot switches. I though I had more, but I didnt.

Honestly though, I think one switch for the channels will be enough, so I might get a small housing from somewhere...

THANKS AGAIN!

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

The switch on the back is a great idea. Glad it's big enough for you. When I built the FS for my Rectoverb I couldn't bring myself to use what I had since I wanted to make sure that I wouldn't switch two switches by accident (large feet... big jumpy guy live...etc...) so I got a bigger one.

However, I also will, eventually, build a simpler one... maybe a 1590b sideways with two switches or a 1590A with only one. Just like you, I don't find many uses for all the options. I rarely switch the reverb on and off and seldom use boost, so a more space-saving smaller switch makes more sense.

As I said, you could also build two switches (with 2 switches each) in smaller enclosures, one with the channel and the other function from the same jack and a second one. That way, if you ever need all four option, you can just get the extra footswitch out of your bag and use it... just my 2cents.

Congrats on your new switch, good job man!

Re: I need an amp footswitch wiring diagram... Ibanez TB100H

any ideas on why it only works when BOTH footswitch inputs are in use? The other cord I plugged in is just a short patch cable (like one you would use between two pedals) Its not even TRS. Its just a normal cord and its not plugged in to anything else.

Well, those TRS jacks can also be used as switches (think of how pedals drain current from the battery when they have a jack in the input while no power's drained when the input jack is unplugged), so I'm guessing that they are linked together and the connection between both needs to be made in order for the switching relays to be activated in the circuit.... that's my theory at least.
Doing what you do is perfectly fine and shouldn't cause problems.
