Bluesbrother +1 on your prayer wish that JTM45/1/12 is what I am talking about too.
There is a dutch amp manufactory that has a new amp out that comes
pretty close to our needs. It is a KOCH Classic SE and comes in 6 watt
or 12 watt and in combo as in a head.
It cost around 779 euro so that is not cheap.
Some times when we are not searching we bump into something special..... Besides blues i also like to play some stuff ala carlos santana
or with a gary moore type of lead sound , man for this type of stuff the
marshall JMD is just perfect.Marshall really made a homerun with that
one .....Surf bought two of these ..... My second wish ...if fender
made such a amp i would really be running to the store to get one,
because the fender amplitube stuff is alread amazing.
All the best ,
bluesbrother.
