Thanks heaps for all of your advice I have a Blackstar HT5-RC tube amp and a Vox VT20X single push/pull tube amp, The Blackstar are very similar to Marshall amps as some members of the Marshall Research and Development team jumped ship and started up Blackstar amps. That is how the story goes anyway. I paid about $1000 Australian Dollars for the HT5-RC - RC stands for Reverb Combo, so I basically have a HT5 head screwed into a cabinet with a terrible I think it is a Blackbird speaker, it is an absolute shocker, so I tend to, at this stage, use the Vox amp much of the time. I intend buying a new 12 inch Celestion Ceramic Vintage 30 - 60 watt speaker and install that in the combo and apparently if I upgrade the Vacuum Tubes (they are Ruby brand at present) with some TungSol or Mullard tubes for the pre amp (12AX7) and perhaps an Electo Harmonix tube in the power amp side the amp may be useable for my purpose which is not full on heavy metal distortion which is the only thing it does well at the moment. I really don't know how the could have got this speaker problem so far from where it should be. Everyone that owns a HT5-R says the same thing to me you have to do the speaker and tube upgrades or they sound awful. So that is the amp situation. Hope that bit of information helps you to pick a pup for my unreal Les Paul Junior, a great guitar.
