My local GC has a Lab Series L5 Amp for $300. Sounded great but I fear it's too big for a bedroom player such as myself. The L3 would likely be preferable;however I do not see any listed for sale. I was also looking for a vintage Roland Jazz Chorus and see their just released the JC22. The JC22 is about the right size and how do the two compare? If I am looking at the Roland should I also consider the Boss Kantana.
