Hi guys. I haven't forgotten about this. I've recently got some bits together to build a test rig, it's not going to be quick but ill post my findings when they occur. What I'm doing to get around it is, I bought the line 6 two button footswitch that switches between the settings in a single bank and a kill switch. So it gives me 'some' control albeit limited. Also, ill use the footswitch to experiment with and find out what's what signal wise. This works for me as I like to mix straight sounds from one amp with effected sounds from the other. There's only so many straight sounds you need, maybe one dirt one clean so blending these with the full effected amp sounds great to me. The only bug bear is I have no volume control over the second amp, which is why I'm still interested in getting this going. Don't lose hope js :0)

Yeah I guess ....

I'm currently investigating a mod to switch two amps. line6 are not being very helpful at all and unless they are willing to impart info on connections and protocols theres not a lot can be done with this or any other mod ideas :0( Shame on Line 6! Ive never had problems getting info from any other amp manufacturer...

Hmm! Line 6 support doesn't seem to be very helpful. They don't want to impart any information but encourage me to use the forum to see if anyone else can help. This just encourages people to trial and error without the proper information which could result in damage or injury. Pretty much any other manufacturer would supply information. It's not like a major product secret surely? It's simply a data connection! That is such a shame,

Just read through this thread again. I think your on the right lines js, but i think it needs more than one wire connected. using a meter on your splitter may help isolate the power wires, i doubt if it would be ac and i would expect it to be no more than 5 volts dc. It could be rs232 connection or more likely rs485 which i'm not totally familiar with. RS 232 is a serial connection and needs two wires to transmit/recieve. You need both I believe due to handshaking. The more i think about it the more i think there is handshaking involved (so both units know the state of the other). Ive requested a service manual from support which they refused, (i'm not surprised) but I've requested specific information on the connection. I don't see why they won't give it but if they don't then this may not be an option for us. I'll keep you posted...

I don't see why this is not possible, a little tricky perhaps but possible. It shouldn't be a problem to provide power externally to the FBV via adapter, even batteries. then its just a point of converting the signal (prob from rs232 or some other protocol) to network protocol, flying through wireless then converting back the other end.

Hi Guys I'd like to jump on board here as this is something i would like to also do. Just wondering, has anyone actually approached line 6 tech support about this and if so what did they have to say about it? I have a background in electronics and before i even had a look on the web i realised there would be problems using network switches etc because of the power required for the fbv. I also found on the web that someone had tried using one and fried their PCB !!!. I haven't tried anything as yet as i want to gather as much info as possible before even attempting. But, to my mind, it should just be a case of isolating the power wires and bussing the receive wires together ( the transmit from the slave amp shouldn't be required). however, what I'm not sure of is if there is any handshake protocol between the amps and FBV's, if so we may all be barking up the wrong tree here. It may be as simple as just bussing the receive (or rather transmit from FBV) wires so it feeds the second amp simultaneously but have all other connections to the slave broken. In this way, i'm guessing that you would connect and power up the first amp to fbv so all power and handshake requirements are met, then connect our fbv transmit buss to an already powered up slave amp. With no other connections made it should respond to commands (unless it requires a completed handshake before it will receive). If it does need to handshake then we will need to find a way to fool it which may be difficult.
