Go to Mercenary dot com and check out the Toft ATC-2 page. Fletcher later clarified his comments by acknowledging that while the Toft pres were not of the standard of "top-of-the-heap" pres, given the price point they should not be expected to be.
TAVD's earlier post is pretty much correct - clean, punchy, transformerless, solid state.......
FWIW, Tchad Blake likes them. As does Tony Visconti.
And further down the phylogenic scale: so do I - great on drums. I also use them for vocals, acoustic guitar, etc when my APIs are tied up.
IIRC the Toft website has links to reviews etc. If you search Gearslutz for Toft ATB and Tchad Blake you'll find Tchad's comments on the Toft pres - which are identical across all Toft products.
