The 1X15 cab is a home made job with a Peavey speaker in. 
I only paid £50 for it and it does the job of beefing up the 2x10 combo. 
 
Im just looking for ideas for what to broaden my search to when/if i get the money to upgrade.  
 
Dont get me wrong I dont dislike the rig or sound its just, as most of us do, I would like to improve it over time.
