I put these on a 30'' custom bass made by a local luthier friend of mine. I really don't understand why this model is cheaper than A or B or D styles. Its is epic, solid, vibrant, resonant, durable, user friendly... I really like the extra mass on sides. looks good and solid. I know it as fact that you need some metal mass on both ends of the string for a good sustain and vibration transfer to and from the wood.
Totally Freakin' Awsome
I put my TransTone on my thirty year old Road Star Ibanez and it plays like new!!! It added some much more in dimension on the tonal quality of that bass!!
