I've been working on classical DB for the past year after over a decade of electric bass. I was going to transition to jazz, but my heart's not there compared to classical and so I've been studying arco technique for the past year. I bought a cello to knock around on last summer and I pick it up every now and then. Well I've been at it a bit more the past few nights and honestly, I think I'm starting to like it over DB. Easier to lug, not physically demanding (size-wise) and I like the tone. There's more repertoire for cello, too. I'm thinking about stopping my DB lessons and taking cello lessons for a year to see how things go. I'll keep the DB for now and put less emphasis on it until I decide if this is a fleeting thought or something longer-term.
