Do you often use Input 2 on Fender blackface style amps?

    I normally play a strat and use input 1 for both the normal and vibrato channels. I found it hard to get a nice clean tone with my humbucker guitars so I decided to plug into input 2. Was pleasantly surprise by very nice clean tones and better balance of tones in all positions on my humbucker equipped guitars. Just wondering if this is a well know/often used approach for folks that play humbucker fitted guitars into Fender blackface type amps?

    Yeah found the same with p90's for any amp with a second or "low" input. Hot rod deluxe, silverface, 65 & 68 reissues, supro, victoria... Now I do it with my strat too sometimes, sounds smooth

    Welcome to the club I also like the second input, it's nice for quieter gigs as well. The second input is for higher output guitars, 1st position is louder for single coil or weaker signal guitars.

    Almost always with my old VR and DR. Been using an old DRII lately. Can't say I discern a notable difference on that one. Regarding the inputs I mean. Obviously the lead channel on the Rivera designs was a different animal altogether from previous Fenders.

    Even when I was primarily a strat guy I plugged into the 2nd input on my Super Reverb l. Don't know why but it seemed slightly mellower than the 1st. Subtle, but preferable to my ears.

    I always use the second input with my HRD. I play a LP or Tele with a mini bucker in the bridge, where I play 95% of the time at my gigs.

    I'll use input 2 for band rehearsals in a small basement.....to keep the volume down.

    This is often overlooked by many of us.

    I used to use the lowly Fender Custom Vibrolux (90s era), and thought "wow, this amp is aggressive". A lot of folks will mod them to mellow them out, but I wonder if they tried the 2nd inputs first? It kind of changes the gain structure of the amp.

    Here's why:
    The #1 input has an input impedance of 1Meg
    The # 2 input is a "voltage divider" with an impedance of (in Fenders case) nominally 136Kohm, and splits the signal at # 2 input by a half.

    So, not only does the # 2 input split the signal it receives by a factor of two, it's impedance (136K ohm) loads-down the output of the guitar. This makes the guitars output a bit smaller. The added loading also reduces the resonant peak of the pickup. This is assuming that the guitar doesn't have a built in buffer or something like that. So, that'll make a big difference in the "bite" of your guitar, it'll smooth it out in most cases.

    The above description is when your guitar is plugged straight into the jack. If your guitar has any pedals between itself and the input jack, then the loading by 136K probably isn't doing much, but the divider still cuts the signal in half, thus backing-off the signal at the grid of the first triode.

    Make sense?

    I'm a fan of input 1...more gain and harmonic overtones. Haven't found a situation where that's a bad thing.

    Always. I play a 1965 Princeton Reverb and our band doesn't play that loud so even into input 2 I don't go above 3. It gives me more control of the volume knob...in the first input, very small changes in the volume knob result in big changes in volume. Plus, my overdrive and fuzz pedals react differently...smoother and more consistent.

    At home I have a Dual Showman Reverb head going into a 2-12 bottom and sometimes I'll play into input 2 for the same reason...more control of the volume knob and a bit of a smoother sound. But other times I like to plug into input 1 and play at ungodly loud volume!

    Another (almost ) always on input 2.

    I go back and forth depending on the guitar I'm playing with my BFPR and SFVR. Single coils into input 1 and HBs into input 2.

    input 2 is really great for bass!

    I appreciate the thorough answer. Is this the same for a tweed fender circuit too? (...specifically a 5F1 champ?)
    Thanks,

    My understanding for the last 40 years is that channel 2 IS for Humbuckers.

    Yep, 5F1 Champ has the same arrangement of input resistors switching jacks.

    Yep, that's precisely why it's there, an option to handle higher output pickups, etc. I use it whenever I need more clean headroom in the preamp section...like on my Champion 600 for example.
