spiderbug 0 Posted June 18, 2015 I bought a line 6 spider iii 30 watt. It powers on but there is no output when you plug a guitar in. but everything lights up and the headphone has out put and aux line in can be heard through head phones. I already tried the reset option of holding clean down. If it is the mainboard were can i get one and for how much? Quote Share this post Link to post Share on other sites
fflbrgst 1,852 Posted June 18, 2015 You would need to troubleshoot the amp, to determine where the problem is. It may be the amplifier section itself, or just the output part. As thi is a rather old amp, an d a smaller model, hopefully you did notpay much for it - or can get a refund from the seller, if they were less than forthright about it.

spiderbug 0 Posted June 27, 2015 paid 20 bucks as is. Can a new mainboard be purchased? If not I'll just convert it to 1x12 cab. Even then it isn't a complete loss 1x12 cabs cost 70 on ebay without a speaker. Quote Share this post Link to post Share on other sites
