Having for example a Focusrite wanted to spend interface just for my first steps in the field of amp modeling on the PC does not necessarily ~ 100, I thought for a sample video on Youtube I try it with this one. And I was not disappointed. According to software only ~ 5ms latency and it feels instant on. Headphone / speaker having to course also be connected to the UCA222 to avoid any additional latency by another output device. However, you also may need a preamp to get a sufficiently strong signal. Again, there is something inexpensive Behringer: Behringer V-Tone Guitar GDI21 Driver DI Is of course in the end the question of what you prefer - these two devices to ~ 50 or just one that as an audio interface and preamp also is good and probably has similar low latency, but will cost a fair bit more. As mentioned at the beginning, I found this solution here better because I could try for the time being so low without preamp if amp modeling at all out of the question via PC for me.
