Is this your first capo ?

maybe the buzz - if usually on the top strings = is possibly due to the strings being set too low to begin with

If using two capos with one biased towards the top strings cures the buzz problem then I am wrong, but you may find it puts the instrument out of tune with the extra bend on the bottom strings

Is the fret board curved while the spider is flat ? if so the two are incompatible

I have always reverted to the shubb capo but I have used and tried most others

£30 is lot

Go to e bay

The also use the G on occasions
