Hi guys. I have Gon Bops Itotole for sale. These were designed per Francisco Aguabella spec's, from what I understand.
Although this is an Itotole, this is a big drum. If you're pairing this with any other drums, other than the Gon Bops, it's an Iya. Measurements are: 7" 1/4' Cha and 11" Enu. Its cha is bigger than the LP Iya, and the enu just an 1.5 inches smaller than the LP. It would be a stretch to fit in there tonally. That being said I have used this as a super tumba when playing congas, as a Iya in a set of bata, or as a drum to lay on the floor and play for rumba with great success. It's got great tone, and a massive slap.
It has a few scratches, but no splits or cracks, and nothing goes very deep. For such an old drum, it's in fine condition.
These are a fairly early model. If you look at the 1973 catalog

I'm not entirely sure of the market for these, but I think $400 is a fair price. PM me here or leave a message if you're interested!
