Started out in the 60s with a Pokerwork DG then moved to a Trichord ADG, then a massive leap to a Guerrini ADG with 5 amazing couplers but absolutely killing to keep it moving in a session (too heavy). In the end about 20 years ago to prevent my arms dropping off I traded it in for a Baffetti dry-tuned DG and learned to play in A on it. Had a loud piercing but pure sound for ceili band, and I now use it mostly for song accompaniment. (Anglo is my main instrument)
