Contact
One person runs this site, reads the inbox, and replies. Email is the way in — here is how to make your message easy to act on.
How to reach Ian
Write to ianwelkins@gmail.com. That address goes directly to Ian Welkins, who builds and maintains Reverb Calculator — there is no support team, ticket system or contact form in between.
A clear subject line helps more than anything else. Something like “Small Room preset at 128 BPM” or “Suggestion: triplet pre-delay” tells Ian which page to open before he even reads the message. If your note is about a specific value, naming the page and the tempo in the first line saves a round of follow-up questions for both of us.
What to write about
Three kinds of message are especially welcome. First, errors: a number that looks wrong, a formula that does not match the Methodology page, or a tool behaving oddly in your browser. Second, suggestions: a missing preset, a note value you reach for that the tools skip, or a small related calculator you wish existed. Third, plain questions about how a value was derived — if the published method is unclear, that is a documentation bug and Ian wants to know.
Business inquiries can go to the same address. Please keep them specific: what you are proposing, for which page, and on what terms. Vague outreach about partnerships or exposure is unlikely to get a reply.
Response expectations
You are writing to a person, not a team, so replies follow a human schedule. Most messages get a reply within a few days; a report that needs numbers re-checked by hand can take a little longer, because the checking happens before the reply, not after it.
If a week passes with no answer, feel free to send a short nudge on the same thread. Nothing here is read by a bot or filtered by a helpdesk system, but a one-person inbox can still bury a message under a busy few days, and a nudge is never rude.
Reporting an error specifically
If you have found a wrong number, a wrong formula or a broken tool, the dedicated Report an Error page lists exactly what to include — the page, your BPM and settings, and the value you expected. Reports written that way can usually be checked in minutes rather than days.
Of course, a plain email to the address above works too. The report page is a shortcut for gathering the right details, not a gate; Ian reads and acts on error reports however they arrive.
Frequently asked questions
Is email really the only way to contact the site?
Yes. There is no contact form, phone number or social inbox for Reverb Calculator. Email keeps everything in one place that Ian actually reads, and it gives you a written record of the reply.
How long does a reply usually take?
Usually within a few days. Simple questions are answered fastest; an error report that needs formulas re-derived by hand can take a bit longer, because the verification happens before Ian writes back.
Can I suggest a new calculator or preset?
Yes, suggestions are genuinely welcome and several tools here started as reader requests. Describe the job the tool should do and the situation you would use it in, and it will be considered for the site.
Do you take business or advertising inquiries?
They can be sent to the same email address, but keep them specific. Note that the site runs no sponsored placements or paid rankings, as the Editorial Policy explains, so offers of that kind will be declined.
What should I include in a correction?
The page name, the exact value you think is wrong, your BPM or room details, and what you calculated instead. That is usually enough for Ian to reproduce the issue and confirm the fix or explain the difference.
