Footswitch circuit in Marshall 2466 100W Vintage Mordern Amp doesn't work. Footswitch OK, Reverb OK, Dynamic Range OK. Just the circuit for switching verb on/off and dynamic range on/off doesn't work. Can you advise or at least send a pdf of the schematic? Thanks so much!

How can I fix reverb?


Either the spring driver circuit blew or the SPRING INSIDE BROKE.
You gotta get in there. Take out the spring unit and check if there is a tensed spring in there. If so, check the connectors. Also check the footswitch plug in the back of the amp, plug and unplug a cable several times, sometimes it becomes dirty and does not let signals through. You can check if the reverb has no drive by tapping the spring while the amp is on and the reverb volume is up. If it sounds, your reverb is fine but not receiving input. That would be the driver circuit. Take it to a Tech and explain.... GOOD LUCK !

Just got a new Marshall DSL40C. The reverb does not work on either gain control or with the footswitch. Why?


Nothing wrong with the amp. Google it- these amps have extremely weak reverb. All of them are the same. It's the one weak point about these amps. And I love mine. I mic it when we gig. Sounds awesome both clean and driven. But you'll have to get a separate reverb pedal if you want "girl crush" or "pipeline" reverb. Don't listen to the above posters. It's the way these amps are.

Marshall MG250dfx problem


Did you already open the amp? Can you send me a closeup picture of the PCB?
Is there any relay? I wonder how the signal is switched between the two pre-amp channels: Either there is a relay (I think so) or the signal is switched directly via the switch on the front. I dont expect optocouplers or switching directly in your footswitch.
So check relay and switch with a circuit / continuity checker

Doesn't work !!


That footswitch is the right one for the HAZ40 but, it is programmable. I recommend downloading the manual and follow the instructions for programming and make sure you are using it properly.

MARSHALL FOOTSWITCH FOR DSL100 TROUBLES


Does your M foot switch work on the Fender? If you know how to use a multimeter you could check continuity by putting meter leads on plug of M foot switch(1 on tip, 1 on sleeve ) You should see a change in the multi meter when you depress switch. If so switch is good. Another easy test is with cap off a spare 1/4 plug -plug it in to foot switch jack.put a alligator or some such metal clip or wire and join(called short or shorting) the two inputs . If connecting and unconnecting results in switching then the foot switch is suspect. One fairly common thing is that foot switch and input jack are often sautered straight to a circuit board to save $ on production cost. Used to be all point to point where a wire was attached to 1/4" input and then wire went to circuit board or tubes. The wire has give, but not so with direct wiring to board. So the nut holding the 1/4" amp input gets loose(doesn't have to be loose for the following to happen) and a pull on the chord causes a break in the soldier and thus a break in the sound chain. Sometimes it will work intermittingly by putting a little pressure left, right, up or down on the plugged in plug. If so, it's the input jacks connection to the amp. If not it still could be that because putting pressure on plug may not be sufficient to affect a temporary reconnection. Since switch(the new one you made)works on Fender, but not Marshall I suspect the jack or foot switch circuitry past the input jack. If using some of the above the above tests leads you that direction,remove housing(unplug a/c power 1st ) inspect jack,wiggle it slightly see or feel a break then resodier from back side. You should be able to use the soldier already present without adding extra.

On the Marshall 5 button footswitch for the TSL, there are 7 wires in the cable, 6 of which are clearly labeled by color on the circuit board in the footswitch. The brown must be combined with another wire...


Only 6 wires are used by the amp. Tie the brown wire to the metal frame to act as shielding if anything. You will probably find that the brown wire either connects to the shell of the connector or to nothing.

First thing is to verify the MAIN power source is getting to the amp. It may not be the fault of the footswitch at all. Connectors and cables are the usual cause of these problems. Seating of connectors is a common problem...

Marshall VS65R is powered up it hums


Blown speaker NO (would not get sound at all)

Bad Reverb UNLIKELY (controls would deselect reverb and it would be out of circuit)
