I have gigged with a secondhand Jim deacon bass £80 IIR,and still use it quite often.I also bought a used Carlsboro Delta bass head £120 IIR,new Behringer 600w 2x12 cab £150,Behringer V-Amp effects unit new £75.All are giggable,so it can be done at guitar store prices.All of these were bought at the same shop,so there was no searching involved.They were'nt all bought at the same time,though they could have been.
