i play a 5 string and i want to know what the heaviest strings out there are i tune real low and want super bright punchy strings, how are the ritter strings?
if you like to tune low but want punchy you might consider custom strings. guys like DR will make those. and the octive4plus.com consider getting a low f string instead of taking a b way down. when you use large strings and tune them down you will loose punch. how low are you going?
