You included the signal path of the kit too, which was an added bonus. The opposite poles of the DPDT make the A/B option very simple and at the same time isolating the 2 circuits.[/quote] Thanks so much for the info! I'm not great with DIY pedals etc but I have a friend who can do this for me. Really really appreciate it! Will get back to you if there are any problems! ed
  2. [quote name='dood' post='53776' date='Sep 1 2007, 12:09 PM']Ok, I have only skim read your post so apologies for the short reply. My first thoughts are that this box will require the necessary program change MIDI messages in order to switch each of it's 4 relays. So, if you are changing every relay at the touch of one button, that controller will have to be able to send those 4 messages at the same time. (rememember you'll have 8 for 4 relays - 4 x on messages and 4 x off messages) I am not aware of any resonably priced MIDI foor controllers that can send any more than one program change message at the same time. There are many that can send multiple CC (constant control) messages but that would still require some sort of environment change, like pushing on a button/controller - these are mostly used for volume and wah pedal type controllers. It maybe easier to get someone with electronic skills to rig up a custom A/B/C mute switch box and stay away from MIDI in this case. It will probably work out cheaper too! - I think with a little bit of design you could come up with a useable option. I would use a selection of DPDT footswitches and work out which preamps you want to switch between. I'd be happy to help if I can, with the design. So... how do you want to mute? do you want to be able to switch between 2 preamps? turn one on when another is off? Or have a 'totally mute' control for tuning?[/quote] thanks for the reply! Sorry, this is a hypothetical situation! I love the sound of the distortion on the AG500, so I was thinking of getting 2 Agro's when they are released in the US, which isn't long, and placing them in the effects loop of the DB750. One for a mild distortion/growl and one for full on dist. As far as I know Agro's are engaged and disengaged by a latching footswitch. Which in total means I have three latching footswitches, one for my DB750 and two for the agro's. So all i'd need is to: 1)mute and unmute my DB750, by muting it everything will be muted and I can tune. 2)Switch between the 1st and 2nd agro. Ideally automatically disengaging one when I engage the other. Being able to control these units simply and easily will affect whether I buy them or not. If it involves three footwitches and 3 cables then Ill just stick to my current pedal board set up - wireless mounted on the board, so only one cable needed from board to amp. Thanks, really appreciate the support! ed
  3. Basically I have 3 units each controlled by their own latching footswitch. (basically its one amp and two pre's each with a mute switch, so all i need is mute/unmute for each of the units) However I would like to control all three with one pedal and one cable. So far I have come across this: [attachment=2028:cfx4_lo.png] It states: -The CFX4 Control Function Switcher can channel switch guitar amps and perform other footswitchable functions via MIDI. -Four isolated relays (prevents ground loop hum/noise) can be individually configured for latched or momentary type switching -Can be used with any MIDI footcontroller capable of sending Program Change or Control Change messages So I could use one midi footswitch to control 3 units. On top of being able to switch each channel on and off independently id like to be able to mute and unmute 2 units at the same time, is this possible if I get the right midi footswitch? Presumably the midi footswitch is able to send the information needed for the unit to latch one unit and unlatch the other at the same time, or latch both at the same time. Sorry if I'm not making complete sense my knowledge of this area is limited. And please, if there is a blindingly obvious way of controlling three units other than this please tell me!! A simple on off, for each of them would suffice if it avoided all this midi stuff. Thanks, Ed
