Hi guys.

I recently became the proud owner of a line 6 spider IV 15 amp.

I seem to have a problem with the channel volume, the sound changes depending on which channel I select (without turning the volume knob) I know you can save the EQ volume and effects settings on each channel, but I have reset everything several times using the instructions that came with the amp, still I get a different volume level with each channel.

I have also noticed that I can change the master volume at any time on any channel, but if I move the channel volume knob the sound fades out. I can still turn the volume up and down, but even on full volume it is very quiet. I get round this by adjusting the channel volume knob to where I want it, then change from one channel to another and back again.

someone else also mentioned that the clean and insane channels both have preset effects that come on even though both the effects knobs are turned all the way off.

you can solve this problem by holding down the insane button when you turn the amp on, but is there any way this can be done without having to hold the insane button down every time you switch the amp on?

as far as the footswitch is concerned, a friend has given me a FBV2 pedal but it doesn't come with a cable. I have found one for sale online for £20 which is just a line 6 RJ45 cable, which is just an ethernet cable isn't it? do you have to use the cable as sold by line 6 or will any RJ45 cable do the same job?

sorry for the long winded first post, I just hope someone is able to help with my problems and questions.
