You must own
ALL OF THEM.
...live long enough and You will - trust me.
Of course You can cut through all the canoli and just get a 5E7 Bandmaster
and You're done - no need for bow-tie-teek - no need for cascading - no need for smaller or bigger - no need for fx - no need for echo - no need for sushi - no need for one twelve or two twelves or four tens or two tens or one fifteen or two fifteens.
Just buy a 5E7 Clone.
Your only needs will be a Cord and a Geetar.
