It depends on what style you like! If it is metal, I suggest you use Nordic handmade single block or Russian handmade single block, but the price is very expensive. The general public is BASS MT-2, which is a classic piece of metal, very good. The new price is generally around 450, and the IBZ signatures of Bloody Mary, Tanks and Steve van are also good. The comprehensive effects are GT6, GT8 and GT65438+. There are many kinds of single overload, besides SD of bass, there are also many kinds of compression, but generally you really want to make everything within 1000 new, and it is unrealistic to have requirements on granularity, effect and timbre. I suggest you dig them out in the second-hand effect area of Guitar China. The prices are very good, and most of them are 9 new things! This is a paradise for rockers to buy and sell each other!
