Can I add a buffer to my effects loop?

For those of you that just like to experiment, adding a buffer like our CLEARLINK (SEND) to an already buffered effects loop will certainly not cause any damage and you may find the results to your liking. However, in the majority of cases, an additional buffer (should your amp already have a buffered effects loop) isn't necessary.See all results for this questionBasel III framework The butterfly effectBasel III framework: The butterfly effect 5 Proposed amendments to MAS Notice 1111 for merchant banks Capital Adequacy Ratio (CAR) The first area of enhancement is to the definition of capital and minimum CAR requirements2.
