Looks great. Would be great if the amps that are not used go into a load so if you don’t forget to standby you don’t risk to damage them.

You've got to remember to put them in standby, or at least disconnect your guitar from its input. Adding a dynamic / reactive load for each unused amplifier output would be extremely expensive, heavy, and would require more space.

​@@therockstudioa static load for a unused amp would be just fine. Just some parallel resistors wiht a reaonable close value

That was really cool! I’ve got the same troubles. 3 heads, 1 4X12”. I think I might try to make my own.

Good idea! I use it every day, saves me a hassle and enables me to be more creative.

A ready-made practical equipment is TC-7220 2-Way Amplifier Speaker Selector, which can work for two amplifiers and two pairs of passive speakers

Just a tech note : the rotary switch power ratings are 28V-500 mA … so That’s a max of 14W. Voltage if roughly ok but current definitely not… be VERY careful as you are clearly overpassing the switch’s ratings.

This is class!

Brilliant.

Awesome build! Looks like it will save you a lot of hassle!

Great video brother! Sorry for the dumb question but I am getting ready to order these parts. Is there an “output” on the rotary switch? Which lugs do you wire to the 1/4” jack for the speaker cabinet? Thank you sir

Wow! Awesome to hear! Sure, each deck on the rotary switch has a pole. The rotary switch for this project has two decks, so it's double pole. The poles will be your outputs, one for positive and one for negative. Be sure to take a look at the datasheet for the switch, and it helps to have a multimeter with a beep/continuity feature with you. I don't have the switch in front of me, and if I didn't specify in the video, use a multimeter to make sure that pin number one is in fact the pole. So for instance on deck one pin 1 is going to be your positive output, deck 2 pin 1 will be your negative output. Pin 2 of each deck will be your positive or negative input from the first amplifier, pin 3 on each deck will be your input for second amplifier, and so forth. If you don't wish to use 11 inputs, you can set the switch to only rotate a few clicks. So there is a metal pin under the washer which you can move to whichever location you desire. Pin number one is always active, when you turn the knob the other pins are connected only when the knob is in that location, so use your continuity tester hooked to pin one on deck one and then the other lead on pin 2. Make sure the knob is all the way counterclockwise and you should hear a beep from your multimeter. Turn the knob one click clockwise, the beep should stop but if you were to move the lead from pin 2 to pin 3, you should hear the beep again. That way you know that pin one is always active and the other pins, two through 12, will only be active when the switch is in that position.

That is really neat !

This is just what I was looking for. The 1/4 TS Jack's you have in your list should be able to handle the power no problem right? Or should I use the one you show on the video. Thank you!

Connectors that I have linked are the ones I used in the video, are they not? Any good quality TS connector will work, whether it be neutrik, amphenol or switchcraft. Thank you so much for watching and commenting! Good luck on your project.

And those toggle switches either are not designed to hold 100W. Be VERY carefull

You seem like a cool dude! Make more videos!

nice

So which 2 wires ( positive and negative ) goes from the switch to the speaker ??

I'm definitely not an expert on electrical output but I'm trying to build the same thing and it looks like the amperage rating on the rotary switch you're using is too low at 500mA. I would think that it would overheat because the amperage coming out of the guitar amps speaker output would be over 4 amps. Have you had any problems since building this box?

@therockstudio

The current carrying capacity of this switch is 15 amps. There is a spec on the switch for make-and-break resistive load which is 500 milliamps at 28 vdc, and 300mA at 120 vac. I believe that only applies if you were trying to switch under load, which does not apply to our purpose. I'll check with them on Monday to find out for sure. I intentionally selected this switch to be heavier than we'd need and 15 amps is well more than enough for our case. Another thing to look at when you're buying a switch is the cost. If this was a plastic-shaft rotary switch, which cost $3, I doubt it would perform at 15 amps. This is a $40 switch, and you get what you pay for. The other rule of thumb to go by is "buy nice or buy twice".

I checked with Electroswitch, I was correct about switching under load. The switch will only pass .3a @ 120vac under load. In a stationary position the switch is rated for 15A. I use mine nearly every day, it has been in use since I made the video. I try to spec-out heavy duty, long lasting parts for anything I build. Thanks for watching.

@@therockstudio Thanks so much for clarifying. I mistook the make-and-break resistive load for overall capacity and trying to find one at 15a was insane. Now I can build this thing without breaking the bank. Thanks again!
