I was thinking about going wireless, seeing as the only lead i have is about 5ft long. My budget is about £100 - £250. My bass is a Squier VM Jazz Bass and i'm thinking of getting a Gallien Krueger 1001rb head, just in case that helps

If you're not prepared to spend more money on the highest quality wireless systems then it's not worth it and will most likely crap out on you.

100-200 could buy you like 10 20 ft leads anyway
