Looking for advice...I own two combo amps - an AI Contra and a Hartke Kickback 15. I would like to try some experiments using both pieces together. I see three options: 1) The Hartke has a 6 ohm 15 inch speaker that could be unhooked from the power amp and plugged into the Contra (I would have to buy a speakon to female 1/4 cable to make the connection) as an extension. XLR out from the Contra to the PA. 2) The Hartke could be slaved to the Contra using the XLR out of the Contra into the input of the Hartke. Then the xlr out of the Hartke could be sent into the PA. 3) The effects send could be sent to the Hartke and I could hook up as in option 1. The two amps are now in seperate locations and I would like to try this without disrupting rehearsal too much. If the good folks here could give me some advice as to the best approach, I could have the apppropriate cabling handy when I went in. BTW I am also electronically challenged and if any of these are not possible, please be kind and keep the flamethrowers on stun. Thanks.
