My favourite OD of those that I have is my Timmy; of those that I've tried and loved but haven't yet acquired, I really like the Wampler Euphoria - it wouldn't replace the Timmy but it'd sit fairly beside it - it's very different. With the right amp (in my small collection, an old SF Twin), my Barber Silver LTD is nice, too. But, my gosh ... I read through these threads and there are just dozens and dozens mentioned that I've never even seen, let alone tried. I have no idea if the Timmy or the Euphoria would compete well with some of these others.
